Need help with Simulatneous Equation.... 1. The problem statement, all variables and given/known data I have a circuit involving nodal analysis. I have the correct nodal equation just need help solving it. v1(1/r1 + 1/r2 + 1/r3) - 10v(1/r1) - v2(1/r3) = 0 v2(1/r3 + 1/r4) - v1(1/r3) = 2A V2 and V1 are my two unknowns. I don't want the answer just a start would be helpful.
