(Solved): The reduced row-echelon form of the augmented matrix for a system of linear equations with variable ...

The reduced row-echelon form of the augmented matrix for a system of linear equations with variables $$x_1,\dots ,x_5$$ is given below. Determine the solutions for the system and enter them below. $$\left[\begin{array}{cccccc}1& 0& 0& ?3& 4& 1\\ 0& 1& 0& ?4& 1& ?4\\ 0& 0& 1& 3& 0& ?5\end{array}\right]$$ You can resize a matrix (when appropriate) by clicking and dragging the bottom-right corner of the matrix. The system has infinitely many solutions Number of Parameters: 1 $$\left[\begin{array}{l}{x}_1\\ x_2\\ x_3\end{array}\right]=\left[\begin{array}{l}0\\ 0\\ 0\end{array}\right]+s\left[\begin{array}{l}0\\ 0\\ 0\end{array}\right]$$
