8x – 2 = -2x + 18
Add +2x to both sides of equation
+2x+8x-2=-2x+2x+18
10x-2=18
Add +2 to both sides of equation
10x+2-2=18+2
10x=20
x=2

8x- 2 = -2x + 18
8x - 2 + 2x = -2x + 2x + 18
10x - 2 = 18
10x - 2 + 2 = 18 + 2
10x = 20
x = 2

Add 2x to both sides to get 10x-2=18; next add 2 to both sides to get:10x=20; finally, divide both sides by 10 to get x=2.
