In matrix there are three type of row operation for transforming the matrix:

1. Swapping the rows: In this operation we can swap any row with any other row.
2. Constant multiplications with row: In this operation we can multiply any non-zero scalar with any row.
3. Subtracting or adding the row: In this operation we can subtract or add another row.

Suppose we have two matrixes A and B. For transforming the matrix A to B we can use three operations.

We can do swapping the rows like$R_i↔R_j$.

We can divide the row by scalar k like $R_i→\frac{R_i}{k}$.

We can add the row like $R_i→R_i-k{R}_j$.

For transforming the matrix B into A we can do the inverse of operation that we have used for transforming the matrix A into B.

If we have used swapping the rows like$R_i↔R_j$ we can do the inverse like $R_j↔R_i$.

If we have used divide the row by scalar k like$R_i→\frac{R_i}{k}$ we can do the inverse like.

$R_j→\frac{R_i}{k}$

If we have used adding the row like$R_i→R_i-k{R}_j$ we can do the inverse like $R_j→R_j-k{R}_i$.

Hence, for transforming the matrix B into A we can do the inverse of operations that we have used for transforming the matrix A into B.
