Solve for X in the equation given. $3 X = - 3 A - B , A = \left[ \begin{array} { c c } - 9 & - 9 \\3 & - 6\end{array} \right] \text { and } B = \left[ \begin{array} { c c } 21 & 12 \\3 & 30\end{array} \right]$

A) $\left[ \begin{array} { c c } 2 & 5 \\- 4 & - 4\end{array} \right]$
B) $\left[ \begin{array} { c c } 6 & 15 \\- 12 & - 12\end{array} \right]$
C) $\left[ \begin{array} { c c } \frac { 1 } { 2 } & \frac { 1 } { 5 } \\- \frac { 1 } { 4 } & - \frac { 1 } { 4 }\end{array} \right]$
D) $\left[ \begin{array} { l l } 2 & - 5 \\4 & - 4\end{array} \right]$
E) $\left[ \begin{array} { l l } 1 & 0 \\0 & 1\end{array} \right]$
