I am having a problem grasping the following matrice problem: (any help is appreciated)

Solve for X given:

10 7 -6 -10 1 6
A= -10 -3 -4 B= -1 -4 0
-8 -5 -9 -5 -2 3

X=4A-4B

How do I start?

If I understand the 'problem' correct it's just multiplying both matrices by 4 (elementswise) and then subtract them (again elementswise)... Don't youuknow how to do that?

Bingo, the light came on after I wrote it and pondered it for a while.

Thanks
