The first step would be to multiply the parenthesis, ex. 5(2x-8) is 10x-40. Once you simplify the equation, you continue to solve it like a regular equation. The equation should look like: 10x-40+15=-15
Me personally I substitute random numbers till I find the correct number, this takes longer but it works best for my understanding. X= 1. 10(1)-40+15=-15. 10-40 is -30, -30+15=-15. So, x=1

Original Equation.

5(2x - 8) + 15 = -15

First do what is in the parenthesis.

2 x 1 = 2

2 - 8 = -6

5(-6) + 15 = -15

Multiply 5 x -6 to get -30

-30 + 15 = -15

add 15 + -30 to get -15

-15

x = 1
