# Unit 5 – Systems of Linear Equations and Inequalities

This unit begins by ensuring that students understand that solutions to equations are points that make the equation true, while solutions to systems make all equations (or inequalities) true.  Graphical and substitution methods for solving systems are reviewed before the development of the Elimination Method.  Modeling with systems of equations and inequalities is stressed.  Finally, we develop the idea of using graphs to help solve equations.
