When solving a 2x3 equation with the matrix system what is the goal? is it to end up with a zero like this?
a b c
0 d e
is that right? or should I also end up with a 1?
If your mean you have a set of equations:
which you are going to solve by reducing the augmented matrix:
by using row opperations.
How you do this depends on what you have been taught, but if you reduce
this to the form:
then is the solution to the original set of equations.
