Solution

\[Given: A + \begin{bmatrix}2 & 3 \\ - 1 & 4\end{bmatrix} = \begin{bmatrix}3 & - 6 \\ - 3 & 8\end{bmatrix}\] 

\[ \Rightarrow A = \begin{bmatrix}3 & - 6 \\ - 3 & 8\end{bmatrix} - \begin{bmatrix}2 & 3 \\ - 1 & 4\end{bmatrix}\] 

\[ \Rightarrow A = \begin{bmatrix}3 - 2 & - 6 - 3 \\ - 3 + 1 & 8 - 4\end{bmatrix}\] 

\[ \Rightarrow A = \begin{bmatrix}1 & - 9 \\ - 2 & 4\end{bmatrix}\]
