Today I taught Hunter about a way to solve a system of equations with determinants. It's called Cramer's Rule. It is easy to do, once you know the process. I also explained to Hunter a little bit about Augmented Matrices. You can write a system of equations in matrix from, and then manipulate the rows to solve the system. We didn't go through the entire process of solving systems with the augmented matrices, but I did show Hunter how to get the systems of equations into augmented form. He did classwork on the desk p. 224 (1-3, 6-7, 9-11)
