Thread: when solving a 2x3 equation applying the matrix system

Hello.

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?

thank you.

You need to be clearer about the exact nature of your question.

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.
