Using Desmos or linear combination method on a scratch piece of paper, solve the system of equations below. State your answer in the form (x, y, z). In the area below prove mathematically this answer is correct. All steps need to be shown to earn full credit. x + 2y - 3z = -2 2x - 2y + z = 7 x + y + 2z = -4

Every time you drive you will experience a combination of driving conditions and environments.

On a piece of paper, graph y< x+1. then determine which answer matches the graph you drew.
