Solving Systems Using Matrices

In my exhilarating trips to Algebra City, Mathland, we learned 2 ways to solve systems. We learned how to solve by elimination and by substitution. But, there is another way. Here is a video on how to solve systems using matrices. This way can be just as useful as the others when solving systems. I remember my days back in 8th grade using matrices. In fact I had a test on solving systems using matrices. What a dreaded day in Algebra City that was. But, I studied hard and in the end did very well. It's a good skill to have.
