-3%2810x-3%29%2B10%283x-3%29=x-7 Start with the given equation



-30x%2B9%2B30x-30=x-7 Distribute


-21=x-7 Combine like terms on the left side


0=x-7%2B21Add 21 to both sides


-x=-7%2B21 Subtract x from both sides


-x=14 Combine like terms on the right side


x=%2814%29%2F%28-1%29 Divide both sides by -1 to isolate x



x=-14 Divide

Answer:
So our answer is x=-14
