Which operations can be applied to a matrix in the process of Gauss-Jordan elimination?

replacing a row with twice that row

replacing a row with the sum of that row and another row

replacing a row with three times another row

swapping rows

replacing a row with the absolute values of that row

Operations that can be applied to a matrix in the process of Gauss Jordan elimination are:

replacing the row with twice that row

replacing a row with the sum of that row and another row

swapping rows

Step-by-step explanation:

Gauss-Jordan Elimination is a matrix based way used to solve linear equations or to find inverse of a matrix.

The elimentary row (or column) operations that can be used are:

1. Swap any two rows (or colums)

2. Add or subtract scalar multiple of one row (column) to another row (column)

as is done in replacing a row with sum of that row and another row.

3. Multiply any row (or column) entirely by a non zero scalar as is done in replacing the row with twice the row, here scalar used = 2
