Chapter 3, Problem 26RE

(a)

To determine

The type of solution for the system of equations (unique solution, no solution, or infinitely many solutions) using the reduced matrix $\left[\begin{array}{ccc}1& 0& -2\\ 0& 1& 3\\ 0& 0& 0\end{array}|\begin{array}{c}6\\ 7\\ 0\end{array}\right]$.

(b)

To determine

A general solution for the system of equations using the reduced matrix, $\left[\begin{array}{ccc}1& 0& -2\\ 0& 1& 3\\ 0& 0& 0\end{array}|\begin{array}{c}6\\ 7\\ 0\end{array}\right]$.
