How to find the inverse of a 3x3 matrix using the method of elementary row operations

For a matrix A, we start of by creating an augmented matrix [ A | I ], where 'I' is the identity matrix. We then apply elementary row operations to transform our augmented matrix to [ I | A^-1 ] to find the inverse of matrix A.

Can we perform both row and column transformation operations or should we use only one that we start with?
