Answer:

I think it is C but it could also be A,like I know it's either because of the lines but I just don't know where the shading should be.What I'm sure of is that B and D are definitely wrong.

Answer:

Step-by-step explanation:

$-7x-3x=-8x-8\\\\-10x=-8x-8\qquad\text{add}\ 8x\ \text{to both sides}\\\\-10x+8x=-8x+8x-8\\\\-2x=-8\qquad\text{divide both sides by (-2)}\\\\\dfrac{-2x}{-2}=\dfrac{-8}{-2}\\\\x=4$
