question 150

Multiple Choice

Given the matrices A and B, solve for X.
- $$2 X = 2 A - B$$
$A = \left[ \begin{array} { r r } - 6 & - 4 \\ 6 & 4 \end{array} \right]$ and $B = \left[ \begin{array} { r r } - 8 & - 18 \\ 6 & 16 \end{array} \right]$

• A) \(\left[ \begin{array} { l l } - 2 & - 5 \\ - 3 & - 4 \end{array} \right]\)
• B) \(\left[ \begin{array} { r r } - 4 & 10 \\ 6 & - 8 \end{array} \right]\)
• C) \(\left[ \begin{array} { r r } - \frac { 1 } { 2 } & \frac { 1 } { 5 } \\ \frac { 1 } { 3 } & - \frac { 1 } { 4 } \end{array} \right]\)
• D) \(\left[ \begin{array} { r r } - 2 & 5 \\ 3 & - 4 \end{array} \right]\)
