In this video lesson, students learn to solve systems of linear equations that involve fractions. Students also learn to solve linear systems of equations by the method of their choice using the following rules: if one of the variables cancels out when the equations are added together, then use addition, and if a variable is already isolated in one of the equations, then use substitution.

This lesson is for ntermediate Algebra Level. In the lesson, Professor Burger shows how to solve systems of equations using a technique known as substitution. In this approach, students solve one equation for one of the variables (eg y) and then plug the value (what y is equal to) into into the other equation (anywhere a y appears). This substitution will allow you to solve for x and then in turn solve for y. Professor Burger walks the viewer through several different types of
examples in the video.
