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.

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.
