[PLAIN]http://img38.imageshack.us/img38/1620/halpwd.jpg [Broken]

2. Relevant equations

I've been simplifying the circuit but with no real objective or guidance. I just don't know how to even begin to show that R and RL are equal. Can someone please help me?

3. The attempt at a solution

This is my work so far. I've just tried simplifying it, but like I said I have no real idea what to do next.
