Solve this equation: 2s + s + 12 = 132.

A. s = 40

B. s = 120

C. s = 9

D. s = - 30

2s + s + 12 = 132

⇒ (2s + s) + 12 = 132 (combine like terms)

⇒ 3s + 12 = 132

⇒ 3s = 132 - 12 (inverse operation)

⇒ 3s = 120

⇒ s = 120/3

⇒ s = 40

Final answer: A. s = 40.

If you would like to solve the equation 2 * s + s + 12 = 132, you can do this using the following steps:

2 * s + s + 12 = 132

3 * s = 132 - 12

3 * s = 120 / 3

s = 120/3

s = 40

The correct result would be A. s = 40.
