Subtract the given matrices, if possible.

[ 56 39 ] [ 44 63 ]
-
[ 45 67 ] [ 38 52 ]

The matrices are:

A = [ 56 39 ]
[ 45 67 ]

B = [ 44 63 ]
[ 38 52 ]

To subtract these matrices, we subtract corresponding elements:

A - B = [ 56 - 44 39 - 63 ]
[ 45 - 38 67 - 52 ]

A - B = [ 12 -24 ]
[ 7 15 ]

Therefore, the difference of the matrices A and B is:

[ 12 -24 ]
[ 7 15 ]
