Question

Solve for x.
9(x + 1) = 25 + x

A.X = 2
B.X = 3
C.X = 4
D.X = 5

Answer 1

x=2

Explanation:

1. Use distribution to simplify

`9(x+1)=25+x\\9x+9=25+x`

2. Move like terms to their respective sides

`9x+9=25+x\\9x=16+x\\8x=16`

3. Solve

`8x=16\\x=2`

Answer 2

x=2

Explanation:

9(x + 1) = 25 + x

9x + 9 = 25 + x [Remove brackets]

8x = 16 [subtract 1x and 9 from both sides]

x = 2
