Suppose that $\vec{p},\vec{q}\text{and}\vec{r}$ are three non-coplanar vectors in $R^3$. Let the components of a vector $\vec{s}$ along $\vec{p},\vec{q}\text{and}\vec{r}$ be 4, 3 and 5, respectively. If the components of this vector $\vec{s}$ along $\left(-\vec{p}+\vec{q}+\vec{r}\right),\left(\vec{p}-\vec{q}+\vec{r}\right)\text{and}\left(-\vec{p}-\vec{q}+\vec{r}\right)$ are x, y and z, respectively, then the value of $2\vec{x}+\vec{y}+\vec{z}$ is
