Solve the system by finding the reduced row-echelon form of the augmented matrix. $\left\{ \begin{array}{ll} 5 x - 2 y - 9 z &= -1 \\ 2 x- y - 3 z &= -1 \end{array}\right.$
reduced row-echelon form:

$\left.\vphantom{\begin{array}{c}\!\strut\\\!\strut\\\!\strut\\\end{array}}\right[$				$\left.\vphantom{\begin{array}{c}\!\strut\\\!\strut\\\end{array}}\right\|$		$\left.\vphantom{\begin{array}{c}\!\strut\\\!\strut\\\!\strut\\\end{array}}\right]$

How many solutions are there to this system?

A. None
B. Exactly 1
C. Exactly 2
D. Exactly 3
E. Infinitely many
F. None of the above

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 $x$ in terms of $z$ in the answer blank for $x$ .

If there are no solutions, leave the answer blanks for $x$ , $y$ and $z$ empty.

$x =$

$y =$

$z =$
