Solve the following system of equations x – y + z = 4, x – 2y + 2z = 9 and 2x + y + 3z = 1.
A. x = -4, y = -3, z = 2
B. x = -1, y = -3, z = 2
C. x = 2, y = 4, z = 6
D. x = 3, y = 6, z = 9
Answer:B
Solve the following system of equations x – y + z = 4, x – 2y + 2z = 9 and 2x + y + 3z = 1.
A. x = -4, y = -3, z = 2 B. x = -1, y = -3, z = 2 C. x = 2, y = 4, z = 6 D. x = 3, y = 6, z = 9
