The image you posted was too large (1599 pixels x 956 pixels), so I deleted it. Please reformat your image so that it is about 800 x 600.

Also, include the given information, preferably as text in this window.

It looks like you have a mistake right at the beginning. I'm assuming that you are given A and B.

If so, A - I =
$$ \begin{bmatrix} 5 - 1 & 3 \\ 3 & 6 - 1\end{bmatrix} = \begin{bmatrix} 4 & 3 \\ 3 & 5\end{bmatrix}$$
