(a)

To determine

To calculate: The system of linear equations represented by $A=\left[\begin{array}{ccccc}4& -2& 2& -3& 0\\ 7& -1& -1& -3& 0\\ 1& 1& 1& -1& 0\end{array}\right]$.

(b)

To determine

To calculate: The solution to the system of equations $\left[\begin{array}{ccccc}4& -2& 2& -3& 0\\ 7& -1& -1& -3& 0\\ 1& 1& 1& -1& 0\end{array}\right]$ by row-echelon method.
