Solving Systems of Linear Equations: Elimination Method

Introduce the inverse matrix method to solve systems of linear equations both algebraically and graphically. Using given data, your class checks their answers with graphing calculators. Handouts are included in this well-thought out lesson.

In this systems of equations worksheet, students use the substitution method to solve systems of linear equations. This one-page worksheet contains eight problems, with answers.

Eleventh graders solve system of linear equations.  In this Algebra II lesson, 11th graders solve s system of linear equations with row reduction to Echelon Form on an augmented matrix.  TI-nspire CAS calculator required.

Middle and high schoolers solve systems of equations relating to money and explore substitution and elimination strategies. In this activity, pupils review The Chicken and Pigs problem and compare their solutions with the graphing...

Solving systems of equations underpins much of advanced algebra, especially linear algebra. Developing an intuition for the kinds and descriptions of solutions is key for success in those later courses. This intuition is exactly what...

Not all systems have a single solution. To begin the video, the narrator reviews the different number of solutions possible with a system of linear equations. He continues with examples of solving systems of equations by graphing. Unlike...

Determine a solution through accurate graphs. Using 2 examples, the narrator walks viewers through the steps to graph a system of linear equations to find the solution. 

This is the first video in a four-part series on explaining, demonstrating, and applying the addition elimination method of solving systems of linear equations. These videos are intended for those who have a firm grasp on graphing...

Linear equations, coordinate planes, and systems of equations are covered in this extremely well-organized instructional activity. Composed of a series of mini-lessons, the instruction aims at explaining a different facet of solving...

Ah, the dreaded systems of equations word problem. Probably one of the best ways to connect algebra to the real-world, here is a video that goes through the steps on how to detect key words and create two equations that model the scenario.
