Do you mean %28x-8%29%2F-7=-8?
Start with
%28x-8%29%2F-7=-8
multiply each side by (-7)
%28-7%29%2A%28%28x-8%29%2F-7%29=%28-8%29%2A%28-7%29
x-8=56
Add 8 to each side.
8%2Bx-8=56%2B8
x=64

Not being sure if you wrote the equation exactly the way it was given,

ADD -%288%2F7%29 to BOTH sides and simplify:
x-%288%2F-7%29%2B%288%2F-7%29=-8%2B%288%2F-7%29
x%2B0=-8%2B%288%2F-7%29
x=-8%2A7%2F7%2B%28-8%2F7%29
x=-56%2F7-8%2F7
highlight%28x=-64%2F7=-9%261%2F7%29
