Write the System of Equations Associated with the Augmented Matrix $\left[ \begin{array} { l l l | r } 1 & 0 & 0 & - 8 \\ 0 & 1 & 0 & - 9 \\ 0 & 0 & 1 & 5 \end{array} \right]$

Write the system of equations associated with the augmented matrix. Do not solve.
- $\left[ \begin{array} { l l l | r } 1 & 0 & 0 & - 8 \\ 0 & 1 & 0 & - 9 \\ 0 & 0 & 1 & 5 \end{array} \right]$

A) $x = - 13$
$y = - 14$
$\mathrm { z } = 0$

B) $x = - 8$
$y = - 9$
$\mathrm { z } = 5$

C) $x = 0$
$y = - 17$
$\mathrm { z } = - 3$

D) $x = 8$
$y = 9$
$\mathrm { z } = - 5$
