Solving Systems of Equations Three Ways

Put all that algebra learning to use! Using algebraic strategies, learners solve three-variable systems. They then use the three-variable systems to write a quadratic equation given three points on the parabola.

Lets keep the system working and show learners the three ways to solve linear systems of equations. Each method includes step-by-step instructions to work their way through the problem. The same problem is used for each method to show...

With 30 problems, each accompanied by a blank graph, pupils get thorough practice solving systems of equations by graphing and finding the point of intersection. Answers are provided in coordinate form.

Sal uses the elimination method to simplify a system of three variables. Next, he employs the substitution method to check his solution. This resource would nicely complement any lesson on this topic.

Sal solves a challenging problem that consists of a system of three trigonometric equations and three unknowns.

How does solving a system of three equations compare to solving two-variable equations? The video tutorial shows how to utilize the same methods of substitution and elimination to solve a system of three equations. The instructor solves...

How many different ways can three planes intersect? The interactive provides three movable planes. Pupils manipulate the planes to determine the number of solutions possible based upon their intersections.

This video demonstrates how to solve a system comprised of three equations in three variables using elimination. [7:00]

This lesson video shows how to solve a system of three equations with three unknown.

Confronted with a system of equations? This tutorial briefly describes the three ways systems of equations can be solved. Substitution, graphing, and the elimination method are all covered. The only thing this video is missing is example...
