Your answer choices are cut off. It appears that choice B isn't shown. However, if
-7x = -56
then
x = 8
the result is positive due to the fact that dividing two negatives (-56 over -7) leads to a positive result. As a check, replace x with 8 to get...
-7x = -56
-7*x = -56
-7*8 = -56
-56 = -56
the fact that we get the same value on both sides confirms we have the right answer.

Answer:
x=9
Step-by-step explanation:
Add similar elements: -5x+3x=-2x
-2x+15=-3
Subtract 15 from both sides
-2x + 15-15=-3-15
Simplify
-2x=-18
Divide both sides by -2
-21/-2 = -18/-2
Simplify
x=9
