I have two equations and two unknowns. The coefficients are complex. How do I solve them using matrices? Or any other method? Here is an example:
Trying to find X and Y
(40 + 50i)(_X_) - 70(_Y_) = 130 -40(_X_) + (170 - 50i)_Y_ = 0
I can do two equations two unknowns on my TI-84 without complex numbers using matricies. It can't do these. I'm new to Mathematica, can anyone help?
