The augmented matrix is Adding times the first row to the second row and subtracting the first row from the third row results in Adding the negative of the second row to the third row results in We evidently end up with an equivalent system of equations Since there is no unique solution, let , where is arbitrary. It follows that , and . Hence all solutions have the form x 5. The augmented matrix is Adding yields times the first row to the second row and adding the fi...
