1.1.2 INTRODUCTION TO SYSTEMS OF LINEAR EQUATIONS Chapter 1: Systems of Linear Equations and Matrices SWBAT: Redefine algebraic operations as Elementary Row Operations. Use Elementary Row operations to solve systems of equations

Brainstorm When working with systems of equations, what are some of the mathematical operations that you are allowed to do? To help you in the process, solve the following system:

Elementary Row Operations Why do we write the equations as rows? Could they just as easily be columns? What are the “elementary Row Operations”

Solve both ways For the following system, use elimination, create an augmented matrix, use the elementary row operations to eliminate. How are the solutions the same?

Problems for mastery pg. 7 8, 10, 11, 12, 13
