Question

-10x - 135 = 117 + 2x A. 25 B. -18 C. -21 D. 22 Helps pls

Answer 1

Answer:

C

Step-by-step explanation:

Add 10x to both sides:

-10x - 135 = 117 + 2x

-10x - 135 + 10x = 117 + 2x + 10x

-135 = 117 + 12x

Subtract 117 from both sides:

-135 - 117 = 117 + 12x - 117

-252 = 12x

Divide both sides by 12:

$\frac{-252}{12} = \frac{12x}{12}$

-21 = x

So the answer is C.

Hope this helps!
