485 + 5 ^ (x + 2) = 12 ^ (2x - 1)(adsbygoogle = window.adsbygoogle || []).push({});

This question is driving me nuts. I can't take the log until both sides have been reduced to one expression each, right? If 485 were a power of 5 or 12, then I'd be able to solve it. As it is, I'm clueless. Can someone walk me through the steps to solving for x?

And if you can't help me there, could you please tell me how to use those nifty image-generating tags for mathematical expressions?
