Is (2, –1, 3) a solution of 3x + 5y – 2z = -5 2х + Зу- z 3D —2 2x + 4y + 6z 18? Replace x with 2, y with -1, and z with 3. Using the first equation, we obtain: 3.2 + 5(-1) – 2(3) 2 -5 6 - 5 – 6 2 -5 -5 = -5, true The ordered triple (2, –1, 3) satisfies the first equation. In a similar manner, you can verify that it satisfies the other two equations and is a solution.
