After this lesson, you will be able to analyze and solve simultaneous linear equations.

The lesson begins by teaching you that a linear equation only has variables raised to the first power. It leads you to learn that simultaneous linear equations can be graphed in on one Cartesian plane. It concludes by showing you that the intersection of the graph of two simultaneous linear equations determines their common solution.

Learn about simultaneous linear equations by helping Thomas and Dieter calculate their monthly sales.

This video includes key concepts, notation, and vocabulary such as linear equation (equation with only variables raised to the first power); simultaneous equations (equations which happen at the same time and can be graphed on the same Cartesian plane); simultaneous solution (a solution to simultaneous equations); and coordinate plane (a plane formed by horizontal and vertical lines called the x- and y-axis).

Before watching this video, you should already be familiar with substitution, point-plotting, and graphing and writing linear equations using variables.

After watching this video, you will be prepared to learn how to solve systems of linear equations algebraically, find solutions by graphing equations, and solve real-world and mathematical problems that use two linear equations in two variables.
