Virtual Nerd: What's a Solution to a System of Linear Equations?

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...

If at first you cannot graph, substitute. The lesson introduces the substitution method as a way to solve linear systems if the point of intersection is hard to determine from a graph. The 28th installment of a 33-part series finishes...

Systematically check a solution in a system. Given a point and a system, the presenter checks to see if the point is a solution to the system. Pupils understand what it means to be a solution to a system. The video shows both...

Picture the solution. The Mathispower4u Algebra I video uses three examples of finding the solution of a system of linear equations given as a graph. Pupils use their knowledge of linear graphs to also identify the equations for the...

Sal teaches how to use graphing as a tool, not a hindrance, in this helpful video. His lecture would make be a good resource for your algebra class, particularly as the focus shifts to graphing problems and linear systems.

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...

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. 

Since the focus of this video is on explaining the solution to a system of equations, the lecturer does not work through the problem. Instead, she points out that the solution should be an ordered pair that makes each equation a true...
