Solve...
:
3%2F%28%28y%5E2-8y%2B7%29%29 - 1%2F%28%28y-1%29%29 = 1%2F%28%287y-49%29%29
Factor:
3%2F%28%28y-7%29%28y-1%29%29 - 1%2F%28%28y-1%29%29 = 1%2F%287%28y-7%29%29
:
Multiply equation by 7(y-1)(y-7), results
7(3) - 7(y-7) = (y-1)
:
21 - 7y + 49 = y - 1
:
21 + 49 + 1 = y + 7y
:
71 = 8y
y = 71%2F8

A rather nasty solution, but it checked out.
