Explanation:
To sum matrices, we add each entry of the first matrix by the corresponding entry of the second matrix. So, the sum of these matrices is equal to
[tex]\begin{bmatrix}{4} & {-2} & \\ {-3} & {6} & {} \\ {7} & {-5} & {}\end{bmatrix}+\begin{bmatrix}{-3} & {10} & \\ {6} & {4} & \\ {-9} & {8} & \end{bmatrix}=\begin{bmatrix}{4+(-3)} & {-2+10} \\ {-3+6} & {6+4} \\ {7+(-9)} & {-5+8}\end{bmatrix}=\begin{bmatrix}{1} & {8} \\ {3} & {10} \\ {-2} & {3}\end{bmatrix}[/tex]
Answer:
Therefore, the answer is the matrix
[tex]\begin{bmatrix}{1} & {8} \\ {3} & {10} \\ {-2} & {3}\end{bmatrix}[/tex]
