question 79

Multiple Choice

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

• A)
• \(X=\left[\begin{array}{rr}
• -2 & -6 \\

• B)
• \(X = \left[ \begin{array} { r r } - 6 & - 2 \\ - 1 & 2 \end{array} \right]\)
• C)
• \(X = \left[ \begin{array} { r r } 2 & - 1 \\ - 2 & - 6 \end{array} \right]\)
• D)
• \[X = \left[ \begin{array} { r r }
• - 1 & - 2 \\
• - 6 & 2
• \end{array} \right]\]
