Write the System of Equations Associated with the Augmented Matrix $\left[ \begin{array} { r r r r } - 8 & - 4 & - 7 & - 6 \\ 4 & 3 & 0 & 6 \\ 8 & 0 & 8 & 2 \end{array} \right]$

Multiple Choice

Write the system of equations associated with the augmented matrix. Do not solve.
- $\left[ \begin{array} { r r r r } - 8 & - 4 & - 7 & - 6 \\ 4 & 3 & 0 & 6 \\ 8 & 0 & 8 & 2 \end{array} \right]$

A) $- 8 x - 4 y - 7 z = - 6$
$4 x + \quad 3 z = 6$
$8 x + 8 y = 2$

B) $- 8 x - 4 y - 7 z = - 6$
$4 x + 3 y + 6 z = 0$
$8 x + 8 y + 2 z = 0$

C) $- 8 x - 4 y - 7 z = - 6$
$4 x + 3 y = 6$
$8 x + 8 y = 2$

D) $- 8 x - 4 y - 7 z = - 6$
$4 x + 3 y = 6$
$8 x + 8 z = 2$
