Forms of linear equations

The row echelon form of a system of linear equations is given.

(a)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 variables.

(b)Determine whether the system is consistent or inconsistent. If it is consistent, give the solution.

$$\begin{bmatrix}0 & -3&|&-4 \\0 & 1&|&0 \end{bmatrix}$$
