1. The problem statement, all variables and given/known data For what value(s) of 'k' will the system have (a) no solution, (b) a unique solution, and (c) infinitely many solutions? x-2y+3z=2 x+y+z=k 2x-y+4z=k^2 2. Relevant equations 3. The attempt at a solution I worked at the matrix and this is what I have so far. I have no idea if I made a mistake along the way, and if not, I am curious on if I thought about the actual answers correctly. I will attach my work so far. Thanks in advance. I will respond to any advice quickly.
