Homework Help: Nodal Analysis Problem, Circuits

  1. Sep 12, 2010 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    Just KVL and KCL equations


    3. The attempt at a solution

    I am having troubling setting this up. I'm not even sure if what I did is right so far. Does anyone know how I set up the equation for V4.

    I am supposed to use nodal analysis but I think I have too many unknowns to be able to find anything. I have VA, VD, but not VB and VC so what do I do?
