    1. The problem statement, all variables and given/known data
    If y element of Reals and (y+1)/y-2) = x, then x ≠ 1.


    2. Relevant equations



    3. The attempt at a solution
    Proof by contradiction. Assume x = 1. Then y + 1 = y -2 or 1 = -2. This is false. It contradicts (y+1)/(y-2)= x. Therefore, x ≠ 1.
