Solve Matrix Equations
-Let $\mathrm { A } = \left[ \begin{array} { r } 1 - 1 \\ - 3 - 1 \end{array} \right]$ and $\mathrm { B } = \left[ \begin{array} { r } - 3 - 4 \\ 1 - 5 \end{array} \right] ; \quad \mathrm { X } + \mathrm { A } = \mathrm { B }$

• A)
• \(X = \left[ \begin{array} { r r } - 4 & - 3 \\ 4 & - 4 \end{array} \right]\)
• B)
• \(X = \left[ \begin{array} { r r } - 3 & - 4 \\ - 4 & 4 \end{array} \right]\)
• C)
• \(X = \left[ \begin{array} { r r } 4 & - 4 \\- 4 & - 3 \end{array} \right]\)
• D)
• \[X = \left[ \begin{array} { r r }
• - 4 & 4 \\
• - 3 & - 4
• \end{array} \right]\]
