For subtracting matrices, their dimension should be equal.

First write the dimension of the matrix.

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

The operation 3B - 2C is possible.

$\"\"$

Multiply the matrix B by 3.

$\"\"$

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

$\"\"$ (Simplify)

$\"\"$

Multiply the matrix C by 2.

$\"\"$

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

$\"\"$ (Simplify)

$\"\"$

Perform the operation 3B - 2C

$\"\"$

$\"\"$ (Subtract corresponding elements)

$\"\"$ (Simplify)

$\"\"$

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