Determine $$3x_{4}+2x_{5}$$, if $$x_{1},x_{2},x_{3},x_{4},x_{5}$$ satisfy the system of equations:

$$\left\{\begin{matrix}2x_{1}+x_{2}+x_{3}+x_{4}+x_{5}=6,\\ x_{1}+2x_{2}+x_{3}+x_{4}+x_{5}=12,\\ x_{1}+x_{2}+2x_{3}+x_{4}+x_{5}=24,\\ x_{1}+x_{2}+x_{3}+2x_{4}+x_{5}=48,\\ x_{1}+x_{2}+x_{3}+x_{4}+2x_{5}=96,\end{matrix}\right.$$
