    Welcome to AAC!

    Part of the problem is you are trying to do it all in one step. This isn't practical.

    Basically keep simplifying and redrawing. As you redraw a simpler circuit it gets easier to solve. Two resistors in series become one, same if two resistors are in parallel.

    For Delta Y configurations (which are tricky) this chapter in the book...

    http://www.allaboutcircuits.com/vol_1/chpt_10/13.html

    will demonstrate how to deal with them.
