will this work to solve complex matrices?

-----------------------------------

So...just brutally [estimated mark ~20% where a pass is 70%] failed an electronics term 2 exam on ac circuits because I completely forgot to study solving complex matrices ...  i smrt... ikr  :cussing: 
Would this method work if I had all of my values in polar form and just carried the angles when solving with cramers rule...ex

2∡63?X + 5∡-90?Y = 5
6∡-25?X + 5∡45?Y = 18

Or would it work if I had them in rectangular form

[2+j5]X + [25-j6]Y = 4
[6- j2]X + [3+ j7]Y = 6

Then convert to polar at the end to divide for the final value....But what would I do with the irrational part? :think: 

Any input or an easier way to do this would be awesome lol... probably wont be able to put it to good use till next year though :/

I would just tend to row-reduce the matrix, it works the same way with complex matrices as with real matrices, except that the scalars are complex.
