Hey, This is a problem involving loop/mesh analysis on an AC circuit. I'm less confused about the circuit theory, I'm more confused with how to solve the resulting matrix. I get 4 equations with 4 unknowns... Which is something I'm accustomed to solving, but there are three different types of terms. Imaginary numbers, real numbers, and the phasor format (magnitude<angle - 4<60) Here's the problem. I solved it the same way this person did, I'm just stuck on the matrix. Any tips on an easy/efficient way to go about this? Thanks!
