How to fill out row echelon form

How to fill out row echelon form:

1. Begin by representing the given system of equations as an augmented matrix. Each row of the matrix represents one equation, and the last column stores the constants.
2. Choose the left-most column with a nonzero entry. This will be the pivot column of the current row.
3. If the entry at the pivot column is zero, swap the current row with a row below it that has a non-zero entry in the same column. This is done to ensure that the pivot entry is non-zero.
4. Divide the current row by the pivot entry to make the pivot entry equal to 1. This is known as row scaling.
5. Use row operations to eliminate any entries below the pivot entry in the same column. This is called row reduction. Subtract multiples of the pivot row from the rows below to make all entries below the pivot entry zero.
6. Move to the next row and choose the left-most column with a non-zero entry as the new pivot column. Repeat steps 3 to 5 until all rows have been processed.
7. The resulting matrix, after performing row scaling and row reduction, is in row echelon form.
