2(3x-6) / (x-1)(x+1) + 1/(x+1) = 4/(x-1)
2(3x-6) / (x-1)(x+1) = 4/(x-1) - 1/(x+1)
2(3x-6) / (x-1)(x+1) = 4(x+1) - 1(x-1) / (x-1)(x+1)
2(3x-6) / (x-1)(x+1) = 4x + 4 - x + 1 / (x-1)(x+1)
6x - 12 / (x-1)(x+1) = 3x + 5 / (x-1)(x+1)
6x - 12 = (3x + 5)(x-1)(x+1) / (x-1)(x+1)
6x - 12 = 3x+5
6x - 3x = 5 + 12
3x = 17
x = 17/3
