Question

9. Solve for x
a. 1-5xl - 5 = 20

Answer 1

`x = 5 \: or \: x = - 5`

Step-by-step explanation

The given absolute value equation is

`| - 5x| - 5 = 20`

We add 5 to both sides of the equation to get:

`| - 5x| - 5 + 5 = 20 + 5`

`| - 5x| = 25`

This implies that,

`- 5x = - 25 \: or \: - 5x = 25`

Divide both sides by -5,

`x = 5 \: or \: x = - 5`
