Answer 1

see attached

Explanation:

Matrix addition, subtraction, and multiplication by a scalar are all done term by term. For example, the (1,1) term of the difference is the difference of (1,1) terms of matrices E and F.

The difference is ...

`\left[\begin{array}{cc}6-(-1)&-2-5\\9-10&4-7\end{array}\right] =\boxed{\left[\begin{array}{cc}7&-7\\-1&-3\end{array}\right] }`
