Which ordered triple (x, y, z) is a solution to the following system of linear equations? x + y - z = 0 2x - y + z = 3 x - 2y + 3z = -1

✓ Correct Answer: Option A

Substitute the values from option A into each equation: (1)+(-5)-(-4) = 0 (True). 2(1)-(-5)+(-4) = 2+5-4 = 3 (True). (1)-2(-5)+3(-4) = 1+10-12 = -1 (True). All equations are satisfied.
