Multiple Choice

Write the system of equations associated with the augmented matrix. Do not solve.
- $$\left[ \begin{array} { r r r | r } 8 & 8 & - 8 & 7 \\6 & 6 & 0 & 9 \\3 & 0 & - 4 & - 6\end{array} \right]$$

• A)
• \[\left\{ \begin{array} { l }
• 8 x + 8 y - 8 z = 7 \\

• 3 x - 4 y = - 6
• \end{array} \right.\]
• B)
• \[\left\{ \begin{array} { r }
• 8 x + 8 y - 8 z = 7 \\
• 6 x + 6 y = 9 \\
• 3 x - 4 z = - 6
