AB =   \left[\begin{array}{ccc}19&2\\43&50\end{array}\right]
|AB| = 19(50) - 2(43) = 950 - 86 = 864
Adjoint AB =   \left[\begin{array}{ccc}50&-2\\-43&19\end{array}\right]
 (AB)^{-1} \frac{1}{|AB|} x Adjoint AB
 \frac{1}{864}  \left[\begin{array}{ccc}50&-2\\-43&19\end{array}\right]
  \left[\begin{array}{ccc} \frac{50}{864} & \frac{-2}{864} \\ \frac{-43}{864} & \frac{19}{864} \end{array}\right]
