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!
which are of little consequence) these are vector equations. For the first you
[4x 3y] = [12 -1]
Now equate componets:
4x = 12,
3y = -1.
So x=3, and y=-1/3.
The second is the same exept you have three componets and so three equations.
