Thread: Solving this equation

Can anyone help me solve this basic equation (including the steps). I know the answer, I just don't know how to get there.

5^9x+2 = (1/25)^2x-9

Excuse the format, don't know how to do exponents on this forum.

Thanks a lot.

I assume the question is

Note that so the RHS becomes

If two bases are the same then their exponents must be the same: . Solve for x

Oh wow, that was so simple. I got it now, thanks a lot.
