$8\textbf{w} + \textbf{v} - 6\textbf{u} = \langle -28, 82 \rangle$

$8\textbf{w} + \textbf{v} - 6\textbf{u} = 8\langle 0,8\rangle + \langle -4,6\rangle - 6\langle 4,-2\rangle = \langle 0,64\rangle + \langle -4,6\rangle + \langle-24, 12 \rangle = \langle 0-4-24, 64+6+12 \rangle = \langle -28, 82 \rangle$
