The inverse of matrix $$ A $$ is $$ A^{-1} = \left[\begin{array}{rrr}5 & -2 & -6 \ 2 & -1 & -3 \ 4 & -2 & -5\end{array}ight] $$.

\( A=\left[\begin{array}{ccc}1 & -2 & 0 \\ 2 & 1 & -3 \\ 0 & -2 & 1\end{array}\right] \begin{array}{c}x-2 y=10 \\ 2 x+y+3 z=8 \\ -2 y+z=7\end{array} \quad \) find \( A-1 \)
