In Problems 25-36, the reduced row echelon form of a system of linear equations is given. Write the system of equations corresponding to the given matrix. Use $x, y$; or $x, y$, z; or $x_1, x_2, x_3, x_4$ as variablex Determine whether the system is consistent or inconsistent. If it is consistent, give the solution.
$\left[\begin{array}{llll|l}1 & 0 & 0 & 0 & 1 \\ 0 & 1 & 0 & 2 & 2 \\ 0 & 0 & 1 & 3 & 0\end{array}\right]$
