-3x-y+2z=1
-x+y-z=2
-x-3y+4z=-3

Answer 1

You'll need to make a choice of method to use in solving this system. You could use elimination of variables. For example, if you were to multiply each the 2nd and the 3rd equation by -3, then you'd be in a position to eliminate x from this system, which in turn would allow you to focus on finding y and z. show your work, please.

Answer 2

Other methods include matrix operations, determinants, substitution.
