You can put this solution on YOUR website!
solve:
:
%283x%29%2F%28x-1%29+%2B+2 = 3%2F%28x-1%29
:
Multiply equation by (x-1) to eliminate the denominators
(x-1)*%283x%29%2F%28x-1%29 + 2(x-1) = (x-1)*3%2F%28x-1%29
cancel out the denominators and you have:
3x + 2x - 2 = 3
:
5x = 3 + 2
x = 5%2F5
x = 1; but this cannot be the solution, it gives us 0 in the denominators
:
It's undefined
