Transform vectors using matrices

The transformation $\text E\,\vec{x}$ is defined by the following matrix. $\text E = \left[\begin{array}{rr}2 & -10 & -6 & 8\\ -3 & 0 & 1 & 5\\ -4 & 2 & 8 &0\\ 2 & -9 & 6 & 5\end{array}\right]$ **Find the result of $\text E\,\vec{v}$ for $\vec{v}=\left[\begin{array}{r}7 \\ 7 \\ 1 \\0\end{array}\right]$.** [[☃ matrix 1]]
