Answer:
x = 1
Step-by-step explanation:
Given
8x - 2(x - 7) = 20 ← distribute parenthesis on left side
8x - 2x + 14 = 20, that is
6x + 14 = 20 ( subtract 14 from both sides )
6x = 6 ( divide both sides by 6 )
x=3
15 – 2x=3x
Add 2x to each side
15 – 2x+2x=3x+2x
15 = 5x
Divide each side by 5
15/5 = 5x/5
3 =x
