I remember from way back in jr high learning that a set of n independent equations is sufficient to determine n unkowns. Lately, I've been a little confused when it comes to complex variables.(adsbygoogle = window.adsbygoogle || []).push({});

My confusion is particularly manifest when dealing with magnitudes and complex conjugation.

I just wanted to get a second oppinion. For example, given two complex valued unkowns w and z, it seems like one should actually consider these as four unkowns, two for the real parts and two more for the imaginary parts. But then again, they can be determined by only two equations. But then again, each equation seems to have two compoents. I don't know how I should think about this.
