Need help rearranging this equation

I'm working on solving a recurrence relation for my discrete math class, and am running into a dead end at the step I thought would be easiest.

I've come up with the equation: A(sub)n = (A(sub)0 p/a)(1+a)^n+p/a

All I need to do now is solve for p, but it's been a while since I took algebra, so no matter which route I take I run into a dead end.

Any help would be greatly appreciated!

Re: Need help rearranging this equation

A(sub)n = (A(sub)0 p/a)(1+a)^n+p/a
A(sub)n= A(sub)n = (A(sub)0)(1+a)^n (p/a)(1+a)^n+p/a
Now find a common factor of p and solve.
