Write matrix A satisfying ` A+[[2 3],[-1 4]] =[[3 6],[- 3 8]]`.
उत्तर
\[Given: A + \begin{bmatrix}2 & 3 \\ - 1 & 4\end{bmatrix} = \begin{bmatrix}3 & - 6 \\ - 3 & 8\end{bmatrix}\]
\[ \Rightarrow A = \begin{bmatrix}3 & - 6 \\ - 3 & 8\end{bmatrix} - \begin{bmatrix}2 & 3 \\ - 1 & 4\end{bmatrix}\]
\[ \Rightarrow A = \begin{bmatrix}3 - 2 & - 6 - 3 \\ - 3 + 1 & 8 - 4\end{bmatrix}\]
