Question

The matrix $\left( \begin{array} { l } 
3 x + y - z = 6 \
2 y + 3 z = 4 \
4 z = 10
\end{array} \right)$ is in echelon form.

Quizplus · Accepted Answer

The given matrix is not in echelon form because it is not a matrix; it is a system of equations. Additionally, echelon form requires a triangular structure, which is not present here.

The Matrix (3x+y−z=62y+3z=44z=10)\left( \begin{array} { l } 3 x + y - z = 6 \\2 y + 3 z = 4 \\4 z = 10\end{array} \right)​3x+y−z=62y+3z=44z=10​​
