I found where I had errored in the first line and did it again, but now I'm stuck again.
x-3...........3x
---- + 4 = ----
x-4............x
x(x-3) + 4x(x-4) = 3x(x-4)
x^2 - 3x + 4x^2 - 16x = 3x^2 - 12x
5x^2 - 19x = 3x^2 -12x
2x^2 - 19x +12x
2x^2 - 7x = 0
That is as far as I got. I don't know if that is right, but I did fix the mistake I had made in my last post. If I did it right, I don't know how to reduce it to just the x value.
