Algebra I: Variables on Both Sides

Objectives

• Students will recognize that linear equations with variables may have none, one, or an infinite number of solutions.
• Students will identify how many solutions a given linear equation with variables on both sides will have.

Vocabulary

• Linear equations
• Variables
• Expressions
• Equation

About the Lesson

The lesson is intended to develop student understanding of the number of possible solutions to equations that have variables on both sides. The activity involves observing that linear equations with variables on both sides can have no solution, one unique solution, or an infinite number of solutions.
