Write the Linear System $$9 x - 2 y = 51$$

Use Inverses to Solve Matrix Equations
Write the linear system as a matrix equation in the form AX = B, where A is the coefficient matrix and B is the
constant matrix.
- $$9 x - 2 y = 51$$
$$6 y = 36$$

A) $\left[ \begin{array} { r r } 9 & - 2 \\ 0 & 6 \end{array} \right] \left[ \begin{array} { l } x \\ y \end{array} \right] = \left[ \begin{array} { l } 51 \\ 36 \end{array} \right]$
B)
$$\left[ \begin{array} { c c } 9 & - 2 \\6 & 36\end{array} \right] \left[ \begin{array} { l } x \\y\end{array} \right] = \left[ \begin{array} { l } 51 \\0\end{array} \right]$$
C)
$$\left[ \begin{array} { c c } 6 & 0 \\9 & - 2\end{array} \right] \left[ \begin{array} { l } x \\y\end{array} \right] = \left[ \begin{array} { c } 36 \\- 2\end{array} \right]$$
D)
$$\left[ \begin{array} { r r } 51 & - 2 \\36 & 0\end{array} \right] \left[ \begin{array} { l } x \\y\end{array} \right] = \left[ \begin{array} { l } 9 \\6\end{array} \right]$$
