Homework Statement
The Attempt at a Solution
I can't figure out how to do this problem. If you set the matrix up like this
2 -1 2 1
3 1 1 1
You can't solve it because there are 3 unknowns and two equations.
I still don't really understand quite well when you set the matrix up vertically or horizontally but if you set it up like this
2 3
-1 1
2 1
there's no place to put the values for x and y to solve things.
