in solving for subtraction under matrices,you must check for their conformability.ie..they must be square matrix for the solution to be solved.
since this matrix is a 2*2 matrix,it is conformable.
\4 -7 / \-9 4 /
\1 8 / - \-1 5/
=\4-(-9) -7-(4)/
\1-(-1) 8-5 / =
\4+9 -7-4/
\1+1 8-5/
=\13 -11/
\2 3 /
