Reduce the matrix A to normal form and hence find its rank where $ A \;=\;\left[ \begin{array}{cccc}0& 1& -3& -1\\1& 0& 4& 3\\3& 1& 0& 2 \\1& 1& -2& 0\end{array}\right] $

R $ _1 \longleftrightarrow R_2 \ \; \ \; \ \therefore A \;=\;\left[ \begin{array}{cccc} 1& 0& 4& 3\ 0& 1& -3& -1\ 3& 1& 0& 2 \ 1& 1& -2& 0 \end{array}\right] \ \; \ \; \ \; \ R_3 \
