Q:
Given the system of equations:
\( \left\{\begin{array}{l}x+y+z=1 \\ y-3 z=-6 \\ 2 x+y+5 z=9\end{array}\right. \)
(a) Determine the type of system: inconsistent dependent
(b) If your answer is dependent, find the complete solution.
Write \( x, y \), and \( z \) as functions of \( t \), where \( z=t \).
If your answer is inconsistent, write DNE in the box for all three variables.
\( x=\square \)
\( y=\square \)
