Solving Rational Expressions - RQD HALP

Hay /sci/.

I've been trying to do this question for well over 2 hours. My friends have tried to help me, but I rejected them, believing I could do it myself. I do realize that the majority of users here are of a college/university math level...so I hope you can understand that we were all once fucking confused and help me out here.

Solve.

x+2 / x-1 + x-4 / x+2 =  x+1/x-1 + 1/2

I have the answer, but I don't know how to solve it. Thanks.

Well, I saw >>1 and thought he must've forgot to put brackets around the spaced apart thingies. Then I saw >>2 and I was confused, because it seemed to imply the lack of brackets was intentional since
(x+2/x-1) + (x-4/x+2) == x+2 / x-1 + x-4 / x+2
but
(x+2/x-1) + (x-4/x+2) != (x+2)/(x-1) + (x-4)/(x+2).

And now I'm retarded? Just learn how to use the notation properly, kthx.
