I have not the slightest idea on how to go about problems when two variables are in the same row:

1) [4x 3y] = [12 -1]

2) [2x 3 3z] = [5 3y 9]

Thanks in advance for the help!

These do not involve matrices (or rather they involve 2x2 or 3x3 identity matrices

which are of little consequence) these are vector equations. For the first you

have:

[4x 3y] = [12 -1]

Now equate componets:

4x = 12,

and:

3y = -1.

So x=3, and y=-1/3.

The second is the same exept you have three componets and so three equations.
