You can put this solution on YOUR website!
2/(x+1) = 1/(x-2) 1
------------------
Cross-multiply to get:
2(x-2) = 1(x+1)
2x-4 = x + 1
x = 5

You did not present your problem clearly, but if you mean:
.
%282%29%2F%28x%2B1%29=%281%29%2F%28x-2%29 . Cross multiply.
.
2x-4=x%2B1 . Subtract x from each side.
.
x-4=1 . Add 4 to each side.
.
x=5
.
CHECK:
For x=5:
.
2%2F%28x%2B1%29=1%2F%28x-2%29
.
2%2F%285%2B1%29=1%2F%285-2%29
.
2%2F6=1%2F3
.
1%2F3=1%2F3
