# Lesson Plan: Applications on Systems of Linear Equations Mathematics • 8th Grade

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to translate a real-life problem into a system of linear equations and find its solution (or solutions).

#### Objectives

Students will be able to

• translate real-life problems into a system of linear equations, solve the system graphically, and understand that the solutions may not be exact,
• translate real-life problems into a system of linear equations and solve the system using
• substitution,
• elimination,
• translate real-life problems into a system of linear equations and show that the system has no solutions.

#### Prerequisites

Students should already be familiar with

• solving systems of linear equations graphically, using substitution and elimination,
• determining the number of solutions in a system of linear equations.

#### Exclusions

Students will not cover

• nonlinear systems,
• systems in more than two variables,
• systems with more than two equations.
