Solving for x help
Can someone please help me out with this.
3^5+2x = 1/9x
I'm not looking just for the answer (since i have it) but i want to understand it.
Here's my rough work.
3^5+2x = 1/ 9^x
= 3^5+2x = 1 / (3^2)^x
5+2x = 2x
0x = 5
... I know i made a mistake somewhere there... the actual answer is x = 5/4 but I have no idea how you get it since the 2 is not negative...
Thanks.

Very badly posted; should be: 3^(5 + 2x) = 1 / 9^x
