Solve the system by finding the reduced row-echelon form of the augmented matrix. -4x+2y-4z = -12 -x-3y + 13z = -17 -x - 3y + 13z = -21 Fill in the blanks for the first 3 columns of the reduced row-echelon form of the augmented matrix: 4 9. How many solutions are there to this system? O A. None OB. Exactly 1 O C. Exactly 2 OD. Exactly 3 O E. Infinitely many OF. None of the above x = 9. y = If there is one solution, give its coordinates in the answer spaces below. If there are infinitely many solutions, enter z in the answer blank for z, enter a formula for y in terms of z in the answer blank for y and enter a formula for æ in terms of z in the answer blank for a. If there are no solutions, leave the answer blanks for æ, y and z empty. 2= *** *** 18 *** ""
