✓
Answer
$6\left[\begin{array}{c}3 \\ -2\end{array}\right]-2\left[\begin{array}{c}-8 \\ 1\end{array}\right]=\left[\begin{array}{c}18 \\ -12\end{array}\right]-\left[\begin{array}{c}-16 \\ 2\end{array}\right]=\left[\begin{array}{c}18+16 \\ -12-2\end{array}\right]=\left[\begin{array}{c}34 \\ -14\end{array}\right]$
