Standards in Unit 2 - Module 1
Reasoning with Equations and Inequalities
Understand solving equations as a process of reasoning and explain the reasoning
MGSE9-12.A.REI.1 Using algebraic properties and the properties of real numbers, justify the steps of a simple, one-solution equation. Students should justify their own steps, or if given two or more steps of an equation, explain the progression from one step to the next using properties.
MGSE9-12.A.REI.3 Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters. For example, given ax + 3 = 7, solve for x.
