How to Solve Inequalities (NancyPi)

Published on September 28, 2018 by

MIT grad explains solving inequalities. This video focuses on solving linear inequalities. It shows when to switch the sign of the inequality, if you divide or multiply by a negative number, and is an introduction to how to solve inequalities in algebra. To skip ahead: 1) For a basic example of SOLVING AN INEQUALITY, skip to time 00:34. 2) For when you have to FLIP THE INEQUALITY SIGN when DIVIDING BY A NEGATIVE number, skip to 1:26. 3) For when you need to reverse the inequality symbol because you're MULTIPLYING BY A NEGATIVE number, skip to 2:42. The problems here are multi-step inequalities, or two-step inequalities. Nancy formerly of MathBFF explains the steps.

Algebraic equations and inequalities: what is inequality math? What does inequality mean? An inequality is a number sentence that uses an inequality symbol instead of an equality symbol (=), which means it has a greater than sign, less than sign, greater than or equal to sign, or less than or equal to sign, instead of the normal equal sign in an equation. One linear inequality definition is: an inequality that involves a linear algebraic expression and inequality signs.

How to find the solution of an inequality algebra problem:

1) A simple, BASIC LINEAR INEQUALITY example you might see on a solving inequalities worksheet or problem set is the expression 2x + 3 [less than or equal to] 11. You can solve for x just like you would for an equality, or normal equation, by trying to get x alone. This is an example of two-step inequalities, or multi-step inequalities. The first step is to subtract the constant 3 from both sides, in order to move it to the right hand side, so that you have 2x [less than or equal to] 8. The second step is to get x alone on the left side by dividing both sides by 2 so that your answer for the inequality is x [less than or equal to] 4. In this case, solving the inequality used the exact same steps you would use to solve an "equal sign" equation.

Sometimes the steps are different from solving normal math equations. Solving for x is the same as solving a linear equality (-2x + 3 = 11) except that if you ever have to divide by a negative number or multiply by a negative number while solving for x, you must flip the sign, or switch the direction of your inequality symbol less than becomes greater than, for example). Here are the two cases of inequality problems WHEN YOU NEED TO REVERSE THE SIGN of the inequality because you're multiplying or dividing both sides of the inequality by a negative number:

2) DIVIDING EXAMPLE: For an inequality like -2x + 3 [less than or equal to] 11, after moving the constant 3 to the right side, you will need to divide both sides by negative 2 in order to get x alone on the left side for the solution. WHEN YOU DIVIDE BY A NEGATIVE NUMBER, you need to reverse the direction of the inequality symbol in your expression. In this example, after you divide out -2, you get x [greater than or equal to] -4 (instead of x less than or equal to -4) for the final solution. This example was also a two-step inequality problem.

3) MULTIPLYING EXAMPLE: For examples like (-1/2)x + 4 [greater than] 7, when you've moved the constant to the right side and have the inequality (-1/2)x [greater than] 3, the fastest way to get x alone is to clear the fraction by multiplying both sides by -2. This will cancel the 2 in the denominator and remove the negative sign in front of x on the left side. But WHEN YOU MULTIPLY BY A NEGATIVE, you have to flip the direction of the inequality symbol so that your answer is x [less than] -6 instead of x [greater than] -6. This problem was also a multi-step inequality.

Note on inequality rules: you don't have to switch the symbol if you're adding a negative number or subtracting a negative number: switching the inequality sign is only for when you're multiplying or dividing by a negative number.

  • Sen484 4 years ago

    Fantastic video again from Nancy but for anyone wondering: Here is why it is flipped.

    Imagine a number line. On the positive side lets say, “56 is greater than 23” (56>23). Then if we multiply both sides by -1, we essentially just change the side of zero they are on. They are still 56 and 23 away from zero, but they’re on the negative side of the number line now. (-56<-23<0<23<56) Essentially, a number larger than another number when positive, is smaller than the other number when they're both negative. Seems basic now I look at it, but didn't grasp it in the video.

      @The Goodly Dragon I do not mean to sound like an egotistic and presumptuous jerk but given that I graduated with honours with a BA in Sociology, I would have to say that it appears that you know little about the complexities of sociological theories. However, I apologize if my presumption is incorrect.
      On a side-note, given the chaos currently occurring throughout the U.S., I would recommend taking a quick look at Das Kapital (1867) by Karl Marx, and The Permanent Revolution (1930) by Leon Trotsky.

    Hi, I had a question in regards to solving this inequality:

    x+1/2x-3 < 1/x-3 Iโ€™m not too sure how to solve it since we donโ€™t know if x is positive or negative so you have to multiply the denominator by x^2

    • Amazing Adam 3 years ago

      This is how I did it:
      (x+1)/(2x+3) < 1/(x-3) If x-3 > 0, x > 3:

      (x+1)(x-3)/(2x+3) < 1 2x+3 must be positive because x > 3

      (x+1)(x-3) < (2x+3) x^2 - 4 x - 6 < 0 If x-3 < 0, x < 3: (x+1)(x-3)/(2x+3) > 1 (flip the sign because x-3 is negative)

      If 2x+3 < 0, 2x < -3, x < -3/2. (x+1)(x-3) < (2x+3) (flip the sign again if x 2x+3 is negative) x^2 - 4 x - 6 < 0 If 2x+3 > 0, 2x > -3, x>-3/2:

      (x+1)(x-3) > (2x+3)

      x^2 – 4 x – 6 < 0 So: If x > 3 then x^2 – 4 x – 6 < 0 If x < -3/2 then x^2 - 4 x - 6 < 0 If -3/2 < x < 3 then x^2 - 4x - 6 > 0

      Solve the inequalities:

      x^2 – 4x – 6 < 0 Complete the square: (x-2)^2 โ‰ก x^2 - 4x + 4 (x-2)^2 - 10 < 0 (x-2)^2 < 10 x-2 < sqrt(10) or 2-x < sqrt(10) (because 2-x and x-2 give the same squared) x-2 < sqrt(10) x < sqrt(10) + 2 or 2-x < sqrt(10) -x < sqrt(10)-2 x > 2-sqrt(10)


      2-sqrt(10) < x < sqrt(10) + 2 This is only true when x > 3 or x < -3/2 so If x > 3:

      2-sqrt(10) < 3 so it cannot be a solution when x > 3.

      So one solution is: 3 < x < sqrt(10)+2 If x < -3/2 then sqrt(10) + 2 cannot be a solution because it is more than -3/2. So another solution is: -3/2 < x < 2-sqrt(10) The solutions for x^2 - 4x - 6 > 0 are:

      (x-2)^2 – 10 > 0

      (x-2)^2 > 10

      x-2 > sqrt(10) or

      2-x > sqrt(10)

      x > sqrt(10) + 2 or

      -x > sqrt(10)-2
      x < 2-sqrt(10) So the solutions to x^2 - 4x - 6 > 0 are:

      x < 2-sqrt(10) x > sqrt(10) + 2

      x^2 – 4x – 6 is only true when -3/2 < x < 3 -3/2 < 2-sqrt(10) sqrt(10) + 2 > 3

      Since both have to be true, there are no values for x that satisfy the inequality when -3/2 < x < 3. So the only solutions to the original inequality (x+1)/(2x+3) < 1/(x-3) are: 3 < x < sqrt(10)+2 or -3/2 < x < 2-sqrt(10) Actually you might have meant x+(1/2x)+3 < (1/x)-3.

  • MrThePsychologist 3 years ago

    have a trouble with (x+3)square>(2x+3) which one is a b and c thanx in advance

    • Amazing Adam 3 years ago

      This is how I would solve it:
      (x-3)^2 > 2x+3


      (x-3)^2 โ‰ก (x-3)(x-3) โ‰ก x^2-6x+9

      x^2 – 6x + 9 > 2x+3

      Move all terms to one side:

      x^2 – 8x + 6 > 0

      Complete the square:

      (x-4)^2 โ‰ก x^2 – 8x + 16

      (x-4)^2 – 10 โ‰ก x^2 – 8x + 6

      (x-4)^2 -10 > 0

      Isolate the square:

      (x-4)^2 > 10

      Square root both sides:

      x-4 > sqrt(10)

      x > sqrt(10)+4

      since (x-4)^2 โ‰ก (4-x)^2, another solution is 4-x > sqrt(10)

      4-x > sqrt(10)

      -x > sqrt(10)-4

      Divide both sides by -1, and flip the signs.

      x < 4-sqrt(10) So the final solutions are: x > sqrt(10)+4
      x < 4-sqrt(10)

    Can we also divide negative half by another negative half

  • inyobill 3 years ago

    I was a little surprised that a justification for reversing the inequality after multiplication by a negative was not given. I always found that that extra insight often helped me remember.

    I watched like 15 different inequality videos before this one and just heard “blah blah combine like terms blah blah subtract blah blah divide blah blah greater than or equal to blah”. And this 5 minute video actually made sense.

    I’m telling yah, hot teacher with a nice voice makes everything easier to learn.

      Certainly doesn’t hurt. If I had more hot teachers in school, maybe I wouldn’t be where I am now!

    You didn’t say where the -2 came from at 3:17 to multiply against the fraction. Is it from the bottom part of that fraction?
