question 27

Multiple Choice

Solve the matrix equation for X.
-Let $A = \left[ \begin{array} { r r } 1 & 4 \\ 0 & - 2 \\ 6 & - 6 \end{array} \right]$ and $B = \left[ \begin{array} { r r } 8 & - 6 \\ - 1 & 4 \\ 0 & 5 \end{array} \right] ; \quad B - X = 3 A$

• A)
• \(X = \left[ \begin{array} { r r } 5 & - 18 \\ - 1 & 10 \\ - 18 & 23 \end{array} \right]\)
• B)
• \(X = \left[ \begin{array} { r r } 11 & 6 \\ 1 & - 2 \\ 18 & - 13 \end{array} \right]\)
• C)
• \(X = \left[ \begin{array} { r r } 5 & - 18 \\ 1 & 10 \\ - 18 & 23 \end{array} \right]\)
• D)
• \(X = \left[ \begin{array} { r r } 11 & 6 \\ 1 & - 2 \\ 6 & - 13 \end{array} \right]\)
