Write the System of Equations Associated with the Augmented Matrix $\left[ \begin{array} { r r r | r } 6 & - 2 & 8 & 8 \\ - 4 & - 4 & 0 & 4 \\ 8 & 0 & 2 & - 5 \end{array} \right]$

Write the system of equations associated with the augmented matrix. Do not solve.
- $\left[ \begin{array} { r r r | r } 6 & - 2 & 8 & 8 \\ - 4 & - 4 & 0 & 4 \\ 8 & 0 & 2 & - 5 \end{array} \right]$

A) $6 x - 2 y + 8 z = 8$
$- 4 x + \quad - 4 z = 4$
$8 x + 2 y = - 5$

B) $6 x - 2 y + 8 z = 8$
$- 4 x - 4 y + 4 z = 0$
$8 x + 2 y - 5 z = 0$

C) $6 x - 2 y + 8 z = 8$
$- 4 x - 4 y = 4$
$8 x + 2 z = - 5$

D) $6 x - 2 y + 8 z = 8$
$- 4 x - 4 y = 4$
$8 x + 2 y = - 5$
