Given the marices;


\begin{gathered} G=\begin{bmatrix}{5} & {6} & {1} \\ {-2} & {4} & {3} \\ {} & {} & {}\end{bmatrix} \\ H=\begin{bmatrix}{-5} & {0} & {} \\ {3} & {9} & {} \\ {2} & {2} & {}\end{bmatrix} \end{gathered}

The order of matrix G is 2x3 while the order of matrix H is 3x2;

The important rule to know is that when adding and subtracting matrices, first make sure the matrices have the same dimensions. In order words, you can add or subtract a 2x3 with a 2x3 or a 3x3 with a 3x3. However, you cannot add a 3x2 with a 2x3 or a 2x2 with a 3x3.

CORRECT OPTION: not possible
