If your solution turns out to be parametric, use (z=t) as the parameter. If no solution exists, explain why not. #28 (Workout - 7 points) Solve the following system of equations algebraically (meaning, by hand). If your solution turns out to be parametric, use (x=t) or (y=t) as the parameter. If no solution exists, explain why.
