Solve the system by finding the reduced row-echelon form of the augmented matrix.
x-4y-2z=2
2x-11y-10z=13
-x+6y+6z=-8
reduced row-echelon form:
1 -4 -2 2
0 1 -10 -3
0 0 0 0
(It's wrong, and I don't know why ? )
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 , enter a formula for in terms of in the answer blank for and enter a formula for in terms of in the answer blank for .
If there are no solutions, leave the answer blanks for , and empty.
How can I find my X, Y ,Z ? Is it going to be Zero ?!
