It's 3/4 = 1 - 3x-2/x+1
3 over 4 = 1 - 3x-2 over x+1
Thanks.

You can put this solution on YOUR website!
3%2F4 = 1 - %28%283x-2%29%29%2F%28%28x%2B1%29%29
Multiply by 4(x+1)
4(x+1)*3%2F4 = 4(x+1)*1 - 4(x+1)*%28%283x-2%29%29%2F%28%28x%2B1%29%29
cancel the denominators, results:
3(x+1) = 4(x+1) - 4(3x-2)
:
multiply what's inside the brackets
3x + 3 = 4x + 4 - 12x + 8
:
Arrange the x's on the left
3x - 4x + 12x = 4 + 8 - 3
:
11x = 9
x = 9%2F11
