Hi guys, I tried a few times to solve this equation, but my result isn't right.

Can someone show me the steps reqired to solve it? Thanks in advance

Show what you tried.

1. Rearrange to equal zero.
2. Take out a common factor in the numerator
3. Use the null factor theorem to address each part individually
4. get your 2 solutions

See image... also x = 1 is an answer. I forgot to write it because i was too busy drawing a whale

oops the image is sideways :P

Additionally, I made a graph of it here:

The link graphs the 2 sides of the equation, and the lines intersect at x = the base cubed

You forgot the cube on the x in your first step. It might make things easier to substitute y = log x and then solve for y first.

(log x + 1)/(log x - 1) = 3(1 - log x)/(log x - 3)
becomes
(y + 1)/(y - 1) = 3(1 - y)/(y - 3)
taking note y can't be 1 or 3, you can multiply both sides by (y - 1)(y - 3) to clear out the denominators.
