The lines L_{1} and L_{2} are defined as

$\begin{array}{l}
L_{1}: \frac{x+2}{-3}=\frac{y-1}{4}=\frac{z+6}{2} \\
L_{2}: \quad \frac{x+2}{6}=\frac{y-1}{2}=\frac{z+6}{-4}
\end{array}$


The plane $ \Pi$ contains both $ L_{1} $ and $ L_{2} $.
1. Find the Cartesian equation of $\Pi$ .2 x+3 z=   

The line$ L_{3} $ is passing through the point $ \mathrm{P}(1,-2,5)$ and perpendicular to$ \Pi $.
2. Find the coordinates of the point where$ L_{3}$ intersects $\Pi$.(a,b,c) a =    b =    c =
