Answer

Final Answer: $The system is inconsistent$

Steps

Step 1 ：The given matrix is in reduced row echelon form. This form corresponds to the system of linear equations: $\begin{aligned} x + 7 z & = 4 \\ y - 9 z & = 5 \\ 0 & = 1 \end{aligned}$

Step 2 ：The third equation, 0 = 1, is a contradiction, which means the system of equations is inconsistent. Therefore, there is no solution for x.

Step 3 ：Final Answer: $The system is inconsistent$

Using the given matrix in reduced row echelon form, determine the solution of the corresponding system of linear equations. Then enter the solution* of x in the box.*If there is a free variable, set z=t and if the system is inconsistent type "inconsistent" in the box.[107401−950001]
