[tex] \frac{4x+4}{3} = 12 [/tex]

Multiply both sides by 3.

4x + 4 = 36

Subtract 4 from both sides.

4x = 32

Divide both sides by 4.

x = 8

Multiply both sides by 3, subtract 4 from both sides, and then divide both sides by 4. (or you could cross multiply)

[tex] \frac{3(4x + 4)}{3} = 3(12) [/tex]

4x + 4 = 36

4x = 32

x = 8
