Q34. Solve the system of equations using matrices (row operations). If the system has no solution, say that it is inconsistent.

3x - 2y = z= -7

  x = y - 2z = 12

3x = y -z = 10

a. x = 2, y = 3, z = -7; (2, 3, -7)

 b. x = 1, y = 3, z = -4; (1, 3, -4)

 c. x = 5, y = 13/2, z = -3; (5, 13/2, -3)

 d. x = 1, y = -3, z = -16; (1, -3, -16)
