Homework Help: Matrice question

  1. Sep 2, 2005 #1
    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
