Writing and Solving Systems of Equations in Story Problems

This video tutorial explains how to solve story problems by writing systems of equations. It covers the basics of systems of equations, including the need for as many equations as there are variables, and the three possible outcomes when solving them. The tutorial also describes three methods for solving systems: graphing, substitution, and elimination. It emphasizes the importance of defining variables and writing equations based on given constraints, using a story problem involving burgers and fries as an example. The video concludes with a discussion on additional constraints, such as non-negative values for variables.
