IM Algebra I: Unit 2 - Linear Equations, Inequalities, and Systems
In this unit, students reason about equations, inequalities, and systems of equations and inequalities as ways to represent constraints, and they reason about the process of solving equations and inequalities in terms of finding values that satisfy those constraints.
