So it would be -5x -10 = 0 right? Then where would I go from there? Because the question I'm doing are quadratic equations and then there's this one which is random and doesn't have the format to do a quadratic calculation on it.

-5x = 10

x = -2 is the answer I've gotten.

The original equation is [(x + 4) / (x +2)] - [(x - 3) / (x - 4)] = 0 and I simplified it to the equation I mentioned in my first post. -2 doesn't fit into the original equation. Maybe I've done something wrong. - Jul 31st 2009, 05:27 PMChris L T521

I thought -16 + 6 is -10? not -22

I'll copy and paste this just in case you didn't see it in my above post:

"The original equation is [(x + 4) / (x +2)] - [(x - 3) / (x - 4)] = 0 and I simplified it to the equation I mentioned in my first post. your answer doesn't fit into the original equation. Maybe I've done something wrong in my calculations."

Note that I've just edited the first (x - 4) to (x +4) in the equation above. It was a typo, so sorry! - Jul 31st 2009, 05:42 PMChris L T521
