Question

Using the techniques discussed in this section, solve the following system of linear equations. Enter the solution as an ordered triple. For parametric solutions use $z = t$ as the parameter. If a solution does not exist, enter DNE for all coordinates.\\ $\begin{cases} -3x - 4y - 7z = 27\\ -y + 3z = -5\\ 4y - 6z = 8 \end{cases}$ \\ $(x, y, z) = (\qquad)$

-3x - 4y - 7z = 27
-y + 3z = -5
4y - 6z = 8

(x, y, z) = ( )
