Chapter 2: Solving One-Step Equations and Inequalities
Lesson Title
Chapter 2.4 Variables and Equations
Pt.1- Classifying Types of Equations
Pt.2- Checking Equations Using Substitution
CA Standards:
Algebra Functions 1.1 -Write an Equation
Algebra Functions 1.4- Use algebraic terms-
equation,open sentence, solution
Objectives:
To classify types of equations
To check equations using substitution

3. Background Info. for the Lesson
1. An equation can be always true, = or An equation can always be false 4 – 3 = or An equation can be open, x + 3 = 7
The equation x + 5 = 8 is an open sentence. When x has a value of 3, then the equation is true… when x has a value of 1, the equation is false. You solve the equation when you find the value for x that makes the equation true… that value is called the solution

4. Prior Knowledge Connection
In Lesson 2.3 you learned to simplify variable expressions.
In this lesson, you will use those skills as you write and solve equations.
Looking Ahead In Lesson 2.5 you will solve equations by adding or subtracting.
