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:

-21 = x
So the answer is C.

Answer:
a, -b
Step-by-step explanation:
When x is a, the function becomes

as you see, a-a is 0, and as your whole function is multiplied by this, it makes it 0.

As you see -b+b is 0, and once again, this would make the whole function 0.
-2/9 x 4/9 is -8
