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 (6B – 2A) is possible.
\Multiply the matrix B by 6.
\
(Multiply each element by 6)
(Simplify
Multiply the matrix A by 2.
\
(Multiply each element by 2)
(Simplify)
Perform the operation 6B-2A
\
(Subtract corresponding elements)
(Simplify)
(6B – 2A)
