Write the Augmented Matrix for the System $$\begin{array} { c } 5 x + 5 y + 7 z = 23 \\- 2 x + 9 y + 4 z = 6 \\2 x + 5 y + 2 z = 16\end{array}$$

Write the augmented matrix for the system. Do not
- $$\begin{array} { c } 5 x + 5 y + 7 z = 23 \\- 2 x + 9 y + 4 z = 6 \\2 x + 5 y + 2 z = 16\end{array}$$

A)
$$\left[ \begin{array} { r r r | r } 5 & 5 & 7 & 23 \\- 2 & 9 & 4 & 6 \\2 & 5 & 2 & 16\end{array} \right]$$

B)
$$\left[ \begin{array} { r r r | r } 5 & - 2 & 2 & 23 \\5 & 9 & 5 & 6 \\7 & 4 & 2 & 16\end{array} \right]$$

C)
$$\left[ \begin{array} { r r r } 5 & 5 & 7 \\- 2 & 9 & 4 \\2 & 5 & 2\end{array} \right]$$

D)
$$\left[ \begin{array} { r r r | r } 23 & 7 & 5 & 5 \\6 & 4 & 9 & - 2 \\16 & 2 & 5 & 2\end{array} \right]$$
