# Algebra I: Balanced Systems of Equations

by Texas Instruments

#### Objectives

• Students will understand what it means for an ordered pair of numbers to be a solution to a single linear equation and to a system of linear equations

#### Vocabulary

• System of linear equations
• Solve

#### About the Lesson

This lesson involves solving systems of linear equations. The emphasis is on helping students understand that the solution to a system of equations is an ordered pair that makes both equations true (or "balances" both equations) at the same time. By using a visual approach to solving the system, students will discover the meaning of a numerical solution to a system of equations. Students will be able to explore systems of linear equations that have infinitely many or no solutions, non-linear systems, and systems with non-integer and negative solutions.
