Solving Systems using Elimination

When guess and check gets old, it's time to start graphing! An instructive lesson explains how to solve a system of linear equations using graphing. Equations are in both slope-intercepts and standard form. 

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...

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. 

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.

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

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...

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...

Confirm the types of solutions by graphing. The video begins with a discussion on the number of solutions and the types of systems by looking at their graphs. Using several examples, the narrator shows the class how to find the solution...

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...

Systems are meant to be solved. An educational video teaches scholars how to graph systems of linear equations to determine whether they have one solution, no solution, or many solutions. They also see how to graph systems of equations...
