​Solve the System of Linear Equations $$\left\{ \begin{array} { l } 4 x + 4 y = 3 \\8 x - 20 y = - 9\end{array} \right.$$

Multiple Choice

​Solve the system of linear equations $$\left\{ \begin{array} { l } 4 x + 4 y = 3 \\8 x - 20 y = - 9\end{array} \right.$$ using an inverse matrix.

A) ​ $$\left[ \begin{array} { l } x \\y\end{array} \right] = \left[ \begin{array} { l } \frac { 3 } { 14 } \\\\\frac { 15 } { 28 }\end{array} \right]$$
B) ​ $$\left[ \begin{array} { l } x \\y\end{array} \right] = \left[ \begin{array} { l } \frac { 9 } { 28 } \\\\\frac { 12 } { 7 }\end{array} \right]$$
C) ​ $$\left[ \begin{array} { l } x \\y\end{array} \right] = \left[ \begin{array} { c } \frac { 9 } { 28 } \\\\\frac { - 3 } { 14 }\end{array} \right]$$
D) ​ $$\left[ \begin{array} { l } x \\y\end{array} \right] = \left[ \begin{array} { c } \frac { 9 } { 7 } \\\\\frac { 15 } { 28 }\end{array} \right]$$
E) ​ $$\left[ \begin{array} { l } x \\y\end{array} \right] = \left[ \begin{array} { c } \frac { - 9 } { 7 } \\\\\frac { - 3 } { 14 }\end{array} \right]$$
