8x/x+1=4-8/x+1
(x+1)8x/x+1=4(x+1)-8/x+1(x+1)
8x=4x+4-8
8x-4x = 4x+4-8-4x
4x = -4
x=-1

Since x = -1, the denominator will be ), which is an undefined # for the equation has NO SOLUTION.
 
I would encourage one thing. First, before ANYTHING else, think about the Domain. I cannot tell WHEN you knew, or how you determined, that x = -1 constituted an inappropriate response. I would prefer an explicit declaration right up front.

Note: You could also add a few more parentheses for greater clarity.

Good work.
