Solve the system of equations using matrices (row operations). If the system has no solution, say that it is inconsistent.
A. x = 3, y = 2, z = 5, w = 5; (3, 2, 5, 5)
B. x = -6, y = 29, z = -36, w = -24; (-6, 29, -36, -24)
C. x = 2, y = 4, z = 1, w = 7; (2, 4, 1, 7)
D. x = 3 + w, y = 2 - 2w, z = 5 + 2w, where w is any real number
