Linear Equations and Matrices

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...

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.

Which method of solving systems is the best? Individuals watch the same system solved using elimination, then substitution, and finally graphing. They can compare the different methods and see how each method results in the same solution.

Elimination is another method for solving systems of equations, in addition to graphing and substitution. Sal's lecture is straightforward to understand, even for students who struggle with learning. By having a variety of options when...

Sal begins this video by "massaging the equations slightly to prepare them for elimination." The equations won't be the only relaxed part of this lesson, which introduces the concept of multiplication to systems of equations. Viewers...

Students will solve systems of linear equations by elimination.

This comprehensive study guide highlights the main terms and formulas needed to review linear systems, specifically solving by elimination. Examples are included.

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...

Twenty problems present a variety of practice using the linear combination/elimination method to solve linear systems. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the problem...

There are many different ways to solve a system of linear equations. In this tutorial, you'll see how to solve a system of linear equations by combining the equations together in order to eliminate one of the variables. Then, see how to...
