Solving Linear Systems of Equations with Matrices ?

You are a high school math teacher and are introducing matrices to the clroom next week. It is very important to you to make a connection between the real world and this topic, so you decide to research in which applications matrices are used. To your surprise, you find several very useful applications, such as decoding and encoding messages, and decide to discuss two that you feel are important to the cl. In the first paragraph, describe the two applications you chose (do not use decoding and encoding) and how they relate to matrices. Then in another paragraph, describe how you would present your lesson to the cl.
