So you would do 5*2x +5*-8 +15=-15
Then simplify so it would be 10x + -40 + 15 = -15
Then add -40 and 15 together
Then it would be 10x + -25 = -15
Then add 25 to -25 and -15
So it would be 10x = 10
And then divide 10 from 10 with would be 1 so x = 1

5(2x-8)+15=-15 (subtract 15 from each side)
5(2x-8)=-30 (divide both sides by 5)
2x-8=-6 (add 8 to each side)
2x=2 (divide both sides by 2)
x=1
