Multiple Choice

Find the inverse of A.​ $$A = \left[ \begin{array} { c c } 2 & 3 \\- 4 & 1\end{array} \right]$$ ​

A) ​ $$A ^ { - 1 } = \left[ \begin{array} { c c } \frac { 1 } { 7 } & - \frac { 3 } { 7 } \\\\\frac { 2 } { 7 } & \frac { 1 } { 7 }\end{array} \right]$$
B) ​ $$A ^ { - 1 } = \left[ \begin{array} { c c } \frac { 1 } { 14 } & - \frac { 3 } { 14 } \\\\\frac { 2 } { 7 } & \frac { 1 } { 7 }\end{array} \right]$$
C) ​ $$A ^ { - 1 } = \left[ \begin{array} { c c } \frac { 1 } { 14 } & - \frac { 3 } { 7 } \\\\\frac { 2 } { 7 } & \frac { 1 } { 14 }\end{array} \right]$$
D) ​ $$A ^ { - 1 } = \left[ \begin{array} { c c } \frac { 1 } { 14 } & \frac { 3 } { 14 } \\\frac { 2 } { 7 } & \frac { 1 } { 7 }\end{array} \right]$$
E) ​ $$A ^ { - 1 } = \left[ \begin{array} { c c } \frac { 1 } { 7 } & - \frac { 3 } { 7 } \\\frac { 2 } { 14 } & \frac { 1 } { 14 }\end{array} \right]$$
