Multiple Choice

Use Inverses to Solve Matrix Equations
- $$\begin{array} { l } - 2 x + 8 y = 60 \\2 x + 8 y = 84\end{array}$$

A)
$\left[ \begin{array} { r r } - 2 & 8 \\ 2 & 8 \end{array} \right] \left[ \begin{array} { l } x \\ y \end{array} \right] = \left[ \begin{array} { l } 60 \\ 84 \end{array} \right]$
B) $\left[ \begin{array} { l l } 60 & 8 \\ 84 & 2 \end{array} \right] \left[ \begin{array} { l } x \\ y \end{array} \right] = \left[ \begin{array} { l } - 2 \\ 8 \end{array} \right]$
C)
$\left[ \begin{array} { c c } - 2 & 2 \\ 8 & 8 \end{array} \right] \left[ \begin{array} { l } x \\ y \end{array} \right] = \left[ \begin{array} { l } 60 \\ 84 \end{array} \right]$
$\left[ \begin{array} { c c } - 2 & 8 \\ 8 & 2 \end{array} \right] \left[ \begin{array} { l } x \\ y \end{array} \right] = \left[ \begin{array} { l } 84 \\ 60 \end{array} \right]$

D)
$\left[\begin{array}{cc}-2 & 8 \\8 & 2\end{array}\right]\left[\begin{array}{l}x \\y\end{array}\right]=\left[\begin{array}{l}84 \\60\end{array}\right]$
