Homework Help: Need help with Nodal Analysis. I have the work, just need a step explained.

  1. Oct 3, 2011 #1
    1. The problem statement, all variables and given/known data


    2. Relevant equations

    V=IR, Nodal Analysis

    3. The attempt at a solution

    1 and 2 in the diagram are the nodal equations. Considering that the left node is V1 and that the right node is V2. I don't know how to get from the nodal equations to step 3. I know that you go from step 3 to step 4 using V=IR.

    I tried solving the nodal equations to get to step 3...

    Can someone please work it out for me? Thank you

    Please help

    In (2) replace Ix with V1/10K. Solve for an expression for V1. Substitute this expression for V1 into (1). Solve for V2. All done.
