Solving Systems of Equations: The Method of Elimination

Published on 06/09/2008

Activity Overview

Whenever a system of n equations with n unknowns is given there are several methods that can be used to find the solution to the system if a solution exists. In this activity, you will use the method of elimination to solve systems of equations.

Before the Activity

  • See the attached PDF file for detailed instructions for this activity.
  • Print pages from the attached PDF file for your class as needed.
  • During the Activity

    Students will:

    • Use the elmination method, solve the system of equations:
    • 5x-3y+4z=19
      3x+5y-4z=7
      -7x+2y-2z=-16

    After the Activity

    Review student results:

    • As a class, discuss questions that appeared to be more challenging
    • Re-teach concepts as necessary
