6x-3=-2x%2B21 Start with the given equation



6x=-2x%2B21%2B3Add 3 to both sides


6x%2B2x=21%2B3 Add 2x to both sides


8x=21%2B3 Combine like terms on the left side


8x=24 Combine like terms on the right side


x=%2824%29%2F%288%29 Divide both sides by 8 to isolate x



x=3 Divide

Answer:
So our answer is x=3


So that means the answer is B)
