SOLUTION
Concept: Matrix Subtraction
When carrying out matrix subtraction or addition, we subtract element occupying corresponding position
The subtraction of the matrix above will produce
[tex]\begin{gathered} -11-(-2)=-11+2=-9 \\ -10-(-1)=-10+1=-9 \\ -4-5=-9 \\ -6-3=-9 \\ -7-2=-9 \\ -8-1=-9 \end{gathered}[/tex]The matrix is writing as
Hence the resulting matrix is a 3 x 2 constant matrix.
