question 164

Short Answer

The matrix is the reduced echelon matrix for a system with variables x 1 , x 2 , x 3 , and x 4 . Find the solution set of the system. $$\left[ \begin{array} { l l l l | l } 1 & 0 & 0 & 7 & 4 \\0 & 1 & 0 & 0 & 7 \\0 & 0 & 1 & 9 & 5 \\0 & 0 & 0 & 0 & 0\end{array} \right]$$ If a system is inconsistent, so indicate.
