(Solved): I need the solution \( Q_{2} \) solve the system \[ \begin{array}{l} x-2 y+z=0 \\ x+y+3 z=0 \\ 2 x+y ...
I need the solution
![\( Q_{2} \) solve the system
\[
\begin{array}{l}
x-2 y+z=0 \\
x+y+3 z=0 \\
2 x+y-z=0
\end{array}

\( Q_{2} \) solve the system \[ \begin{array}{l} x-2 y+z=0 \\ x+y+3 z=0 \\ 2 x+y-z=0 \end{array} \]
\( Q_{3} \) solve the system \[ \begin{aligned} 1 / x+2 / y-4 / z &=1 \\ 2 / x+3 / y+8 / z_{z} &=0 \\ -1 / x+9 / y+10 / z_{z} &=5 \end{aligned} \]
