Homework Help: Possible to simplify or transform source in circuit

  1. Sep 17, 2016 #1
    1. The problem statement, all variables and given/known data
    I have to do nodal analysis and I was wondering if there is any transformations or simplifications I can do to the circuit. In this class we are supposed to be able to look at the circuit and input what we need into the matrix based on just looking at it. I am not sure that I did it correctly here.
    2. Relevant equations

    3. The attempt at a solution
    See attached file for my work (blue lines separate each entry of the matrix). problemsolv.png

    Its been a long time since I've taken these classes but I'll take a look-

    I'm looking at your diagram. Where are i2, i3, and i4?
