This isn't linear algebra.

FALSE ADVERTISING.

Linear refers to the biggest power being 1. This is the case. This is linear algebra. I don't quiet know what you're asking, but in those equations. x will have a value, y will have a value and so will z. If they are solved simultaneously. 

Question B isn't clear to me.

solved A, yes only 1 solution. B, if det = 0, solution is undefined. Answer: 3
