Answer:
The two matrices cannot be added
Explanation:
Given the sum of the matrices;
[tex]\begin{bmatrix}{1} & -6 & \\ {9} & {7} & \\ {5} & {3} & \end{bmatrix}+\begin{bmatrix}{0} & {3} & {6} \\ {1} & {4} & {9} \\ {2} & {5} & {8}\end{bmatrix}[/tex]
You can see that the first matrices is a 2 * 3 matrices while the second matrices is a 3*3 matrices. Note that before you can add two matrices together, they must have the same dimension.
Since the dimension of the matrices are not the same, hence they cannot be added.
