Use elementary row operations to find the inverse of \left[\begin{matrix}-2 & -1 & 3 \\ 4 & -2 & 1 \\ 0 & 4 & -2\end{matrix}\right] I know the inverse as I've done it via cofactor and adjugate. And wolframalpha has confirmed the result. But no matter how many times I try with the elementary row operations I can't get it right.
