Problem 45: Matrix Invertion with Adjoints

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
Given the matrices

$\displaystyle A=\left(\begin{array}{rrr} 7 & 2 & 3 \\ 8 & 1 & 4 \\ -12 & -4 & -... ... & 4 \\ 2 & 0 & 0 & 0 \\ 0 & 0 & -3 & 0 \\ -2 & 0 & 0 & -1 \end{array}\right). $

Use the adjoints $ \tilde{a}_{ij}$ and $ \tilde{b}_{ij}$ to find $ A^{-1}$ and $ B^{-1}$.
