Find the Inverse Matrix of A $$A = \left[ \begin{array} { r r } - 2 & 3 \\- 6 & - 6\end{array} \right]$$

Find the inverse matrix of A.
- $$A = \left[ \begin{array} { r r } - 2 & 3 \\- 6 & - 6\end{array} \right]$$

A) $\left[ \begin{array} { c c } - \frac { 1 } { 5 } & \frac { 1 } { 10 } \\ - \frac { 1 } { 5 } & - \frac { 1 } { 15 } \end{array} \right]$
B) $\left[ \begin{array} { c } \frac { 1 } { 5 } - \frac { 1 } { 15 } \\ - \frac { 1 } { 5 } - \frac { 1 } { 10 } \end{array} \right]$
C)
$\left[\begin{array}{r}-\frac{1}{15}-\frac{1}{10} \\\frac{1}{5}-\frac{1}{5}\end{array}\right]$

D) $\left[ \begin{array} { c } - \frac { 1 } { 5 } - \frac { 1 } { 10 } \\ \frac { 1 } { 5 } - \frac { 1 } { 15 } \end{array} \right]$
