Solve Matrix Equations
-Let $\mathrm { A } = \left[ \begin{array} { c r } 4 & 5 \\ 0 & 3 \\ 9 & - 9 \end{array} \right]$ and $\mathrm { B } = \left[ \begin{array} { r r } 9 & - 9 \\ - 4 & 5 \\ 0 & 8 \end{array} \right] ; \quad \mathrm { B } - \mathrm { X } = 3 \mathrm {~A}$

• A)
• \(X = \left[ \begin{array} { c c } - 3 & - 24 \\ - 4 & - 4 \\ - 27 & 35 \end{array} \right]\)
• B)
• \(X = \left[ \begin{array} { r r } 21 & 6 \\ 4 & 14 \\ 27 & - 19 \end{array} \right]\)
• C)
• \(X = \left[ \begin{array} { r r } - 3 & - 24 \\ 4 & - 4 \\ - 27 & 35 \end{array} \right]\)
• D)
• \(X = \left[ \begin{array} { r r } 21 & 6 \\ 4 & 14 \\ 9 & - 19 \end{array} \right]\)
