Question

Consider the following absolute value equation. |5x-4| > 16. Which of the following are the solutions to the equation? Select ALL that apply.
1. -5
2. -7
3. -3
4. 0
5. 3
6. 5

Answer 1

|5x - 4| > 16

5x - 4 > 16                     or                  5x - 4 < - 16
Add 4 to both sides
5x > 20                                                5x < -12
Divide both sides by 5
x > 4                              or                    x < -12/5, x < -2.4
