Let $$\vec{w} = \left<-10,-2\right>, \ \vec{v}_1 = \left<-3,3\right>, \ \vec{v}_2 = \left<1,5\right>, \ \vec{v}_3 = \left<-3,-3\right>.$$ If possible, express $\vec{w}$ as a linear combination of the vectors $\vec{v}_1, \vec{v}_2$ and $\vec{v}_3$. Otherwise, enter DNE. For example, the answer $\vec{w} = 4 \vec{v}_1 + 5 \vec{v}_2 + 6 \vec{v}_3$ would be entered $\verb!4v1 + 5v2 + 6v3!$.

$\vec{w} =$
