Modulus inequalities

In the following videos I introduce you to solving modulus inequalities of different types. I am assuming that you are already familiar with the methods used in solving mod equations.

Examples: Solve

  1. |4x - 3|>5
  2. |3x+2|<4
  3. |3-5x|<7

In this video I show you how to solve inequalities where we have two functions of x being ‘modded’ by graphical and calculation methods.

Example: Solve

  1. |2x-3|>|x+3|

Lastly, I show you how to solve a function of x on one side of the inequality and on the other a function of x which is ‘modded’. Again there are two methods of solution, but you need to take care with these.

Example: Solve

  1. x+6 > |3x+2|
