Solve the system of equations using matrices (row operations). If the system has no solution, say that it is inconsistent.
A. x = 2, y = 3, z = -6, w = 7; (2, 3, -6, 7)
B. x = 3, y = 1, z = -2, w = 5; (3, 1, -2, 5)
C. x = 3 + w, y = 1 - 2w, z = -2 + 2w, where w is any real number
D. x = 5, y = 21, z = -14, w = -2; (5, 21, -14, -2)
