Question

Solve this equation: 2s + s + 12 = 132.
A. s = –30
B. s = 120
C. s = 9
D. s = 40

Answer 1

solve your equation step-by-step.

2s+s+12=132

Simplify both sides of the equation.

2s+s+12=132

Simplify:

3s+12=132

Subtract 12 from both sides.

3s+12−12=132−12

3s=120

Divide both sides by 3.

3s/3 = 120/3

s=40
