Systems of Equations

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...

The solution resides at the intersection. Pupils use a short instructional activity to review the process of solving a system of linear equations using graphing. The instructional activity provides completed graphs for most of the items,...

Get to graphing and figure out the solution between two lines using this 14-problem worksheet. Graphs are provided for the first eight problems, but requires learners to graph the remaining six separately.

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.

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. 

Another method for solving systems of equations, in addition to graphing, is the focus of this video, as Sal demonstrates the substitution method. It's important to understand that there is more than one way to solve any problem,...

Is the solution really the solution? Given a graph of a linear system, an informative video shows learners how to determine the solution as the point of intersection. The presenter verifies the solution as a solution to the system by...

So, exactly, what does it look like? The easily usable graphing calculator allows pupils to visualize the graph of equations and inequalities. The interactive supports any algebraic graph needed for high school mathematics and then some.

Twenty problems present a variety of practice solving systems of linear equations by graphing. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the problem then click the "View...
