10x - 40 + 15 = -15 (use distributive)
10x - 25 = -15. add integers on left

Answer:

x = 1

Step-by-step explanation:

Given

5(2x - 8) + 15 = - 15 ( subtract 15 from both sides )

5(2x - 8) = - 30 ( divide both sides by 5 )

2x - 8 = - 6 ( add 8 to both sides )

2x = 2 ( divide both sides by 2 )

x = 1
