[tex]~~~~~A+\begin{bmatrix}3 & 9 & -1&-8\\16 & -2 & 3&13\end{bmatrix}=\begin{bmatrix}0 & -5 & 6&10\\3 & 0 & -2&7\end{bmatrix}\\\\\\\implies A = \begin{bmatrix}0 & -5 & 6&10\\3 & 0 & -2&7\end{bmatrix}-\begin{bmatrix}3 & 9 & -1&-8\\16 & -2 & 3&13 \end{bmatrix}\\\\\\\implies A = \begin{bmatrix} 0-3&-5-9&6+1&10+8\\ 3-16&0+2&-2-3&7-13 \end{bmatrix}\\\\\\\implies A= \begin{bmatrix}-3&-14&7&18\\-13&2&-5&-6 \end{bmatrix}[/tex]
