For subtracting matrices, their dimension should be equal.

First write the dimension of the matrix.

The dimensions of matrix A and B are $\"\"$ .

The operation 3B $\"\"$ 2A is possible. $\"\"$

Multiply the matrix B by 3.

$\"\"$

$\"\"$ (Multiply each element by 3)

$\"\"$ $\"\"$

Multiply the matrix A by 2.

$\"\"$

$\"\"$ (Multiply each element by 2)

$\"\"$ $\"\"$

Perform the operation 3B $\"\"$ 2A.

$\"\"$

$\"\"$ (Subtract corresponding elements) \ \ $\"\"$ (Simplify) $\"\"$

The value of (3B $\"\"$ 2A) is $\"\"$ .
