%283%2F8%29x-7=5%28-x%2B1%29 Start with the given equation.


%283%2F8%29x-7=-5x%2B5 Distribute.


8%28%283%2Fcross%288%29%29x-7%29=8%28-5x%2B5%29 Multiply both sides by the LCD 8 to clear any fractions.


3x-56=-40x%2B40 Distribute and multiply.


3x=-40x%2B40%2B56 Add 56 to both sides.


3x%2B40x=40%2B56 Add 40x to both sides.


43x=40%2B56 Combine like terms on the left side.


43x=96 Combine like terms on the right side.


x=%2896%29%2F%2843%29 Divide both sides by 43 to isolate x.

Answer:

So the answer is x=96%2F43


Which approximates to x=2.233
