**Course Description**

This course will cover different methods of solving systems of equations. It will start with basic two variable systems and progress to three variable systems. The three variable systems of equations will be the majority of the course. Two methods will be taught and reviewed. You will also see applications of systems of equations through word problems. The course will end with a brief introduction for matrices, another application for systems of equations.

**Course Goals**

Upon completion, the student will have an understanding of how to solve systems of equations using a variety of different methods. The student will also understand how to apply solving systems of equations to real-world problems.

**Target Audience**

This course is targeted towards 10th and 11th graders. It is mainly for students taking Algebra II.

**Course Requirements**

Students taking this course should have a strong understanding of algebra.
