Solve.
-x + y + z = 1 x - y + 2z = 8
2x + y + z = -2
(5, -1, -3)

Question

Quizplus · Accepted Answer

To verify if the solution (5, -1, -3) is correct, we substitute x=5, y=-1, and z=-3 into each equation:1. For x + y + z = 1: 5 - 1 - 3 = 1, which simplifies to 1 = 1. This is true.2. For x - y + 2z = 8: 5 - (-1) + 2(-3) = 5 + 1 - 6 = 0, not 8. This is false.3. For 2x + y + z = -2: 2(5) - 1 - 3 = 10 - 1 - 3 = 6, not -2. This is false.Since the solution does not satisfy all the equations, the answer is No.
