Hi;

It is not safe to post your email like that. It can be easily seen by hackers and spammers.

It wont let me post the pictures for the lesson.

Please provide a link or is the material on your machine?

That you can not upload as an image. You must hand copy what you want me to look at.

12. [[ 9   -4         [[ -37 -75
      [ -3  -8]]  X=  [  115  -3]]

13. [[ 11  1          [[-119  17
       [-6  10]] X=  [ -30  54]]

14. [[ -8 6          [[ 12  16
       [ -3 -6]]  X=[  87  27]]

15. [[ -3  9        [[ -51  -87
       [ 11 7]] X= [ -173  79]]

16. [[ 7  -6          [[ 7  -16

Re: Solve The Matrix Equation For X

That is a lot of problems that all use the same method. While I am gone you will learn how to multiply matrices from here:

Re: Solve The Matrix Equation For X

You still are not able to multiply 2 matrices?

Then all I can do is give you the answers.
