The system of linear equations are $\"\"$ .

The system of linear equations can be written as the form of augmented matrix.

$\"\"$

Now we can apply elementary row operations.

Now the matrix is in reduced row-echelon form.

Converting back to a system of linear equations we have $\"\"$

The solution is $\"\"$ , y = 3 and ordered pair is $\"\"$ . $\"\"$

The solution is $\"\"$ , y = 3 and ordered pair is $\"\"$ .
