This chapter kicks off with learning what systems of linear equations are and how they can be represented and solved by graphing. You will then shuttle over to learning the two core methods for solving systems of linear equations: substitution and elimination. From here you will learn how to translate word problems into systems of linear equations in order to solve the word problems. The last several sections of the chapter will have you learning how to graph linear inequalities and systems of inequalities before finishing up with a lesson on linear inequality word problems. Go see just how great you can be at systems!!
