Presentation transcript:

Reasoning with linear equations and inequalities Students will understand that equation is a statement of equality between two expression. Students find values to sign to the variables to make the statement true

Standards A.REI.1 using algebraic properties and the properties of real numbers justify the steps of a simple one solution equation A.REI.3 solve linear equations in one variable including equations with coefficients represented by letters

Essential Questions What is the purpose of using variables? When we solve an equation what does it tell us?

Vocabulary words Equation:Variable: Properties of equality: Statement saying two things are equal A symbol or letter in an equation Has an equal sign

Solve 2x = 12

What is our goal to solve these equations? Find x!!!

Put steps in order to solve: 4x - 11 = 42 - x Add 11 to both sides Steps Divide by 5 Get all x on one side
