- $$\mathbf { b } _ { 1 } = \left[ \begin{array} { r } 1 \\- 2\end{array} \right] , \mathbf { b } _ { 2 } = \left[ \begin{array} { r } - 5 \\3\end{array} \right] , \mathbf { x } = \left[ \begin{array} { r } 22 \\- 16\end{array} \right]$$

• A) \( \left[\begin{array}{r}-4 \\ 1\end{array}\right] \)
• B) \( \left[\begin{array}{r}-2 \\ 4\end{array}\right] \)
• C)\( \left[\begin{array}{r}2 \\ -4\end{array}\right] \)
• D)\( \left[\begin{array}{r}-4 \\ 2\end{array}\right] \)
