Question

Solve for x.

9(x + 1) = 25 + x

A X=2

B X=3

C X=4

D X=5

Answer 1

9(x + 1) = 25 + x

First, get rid of your parenthesis on the left side of your equation.

9x + 9 = 25 + x

Subtract x from both sides

9x - x + 9 = 25 + x - x

8x + 9 = 25

Subtract 9 from both sides

8x + 9 - 9 = 25 - 9

8x = 16

Divide both sides by 8

8x ÷ 8 = 16 ÷ 8

x = 2.

Answer 2

9x + 9 = 25 + x

8x = 16

x=2
