In this lesson, students will learn how to set up systems of equations to solve word problems. The video emphasizes how to define two variables and write two equations to comprise a system, with a focus on how to check the answer. Examples are given for word problems involving numbers and stamps that require the use of a chart to organize the information. Students are encouraged to pause the video and solve the system using either the substitution or addition method, with the steps on solving the system covered in other videos.
