Practice problem
Given the matrix A=[537249296]A=\begin{bmatrix}5&3&7\\2&4&9\\2&9&6\end{bmatrix}A=522349796, perform the row operation: R3⟷R2R_3\longleftrightarrow R_2R3⟷R2
[537296249]\begin{bmatrix}5&3&7\\2&9&6\\2&4&9\end{bmatrix}522394769
[246296537]\begin{bmatrix}2&4&6\\2&9&6\\5&3&7\end{bmatrix}225493667
[537296296]\begin{bmatrix}5&3&7\\2&9&6\\2&9&6\end{bmatrix}522399766
[573294269]\begin{bmatrix}5&7&3\\2&9&4\\2&6&9\end{bmatrix}522796349
