1.	Suppose that p,q and r are three non-coplanar vectors in R3. Let the components of a vector s along p, q and r be 4, 3 and 5 respectively. If the components of this vector s along (-p+q+r), (p-q+r) and (-p-q+r) are x, y and z respectively, then the value of 2x+y+z is ___
Answer» Suppose that p,q and r are three non-coplanar vectors in $R^{3}$ . Let the components of a vector s along p, q and r be 4, 3 and 5 respectively. If the components of this vector s along (-p+q+r), (p-q+r) and (-p-q+r) are $x$ , $y$ and $z$ respectively, then the value of $2 x + y + z$ is ___
