Algebra 49 - Three Variable Systems in the Real World - Problem 1

The video tutorial introduces systems of linear equations, starting with two equations in two variables to solve real-world problems, such as calculating the price of movie tickets and drinks. It then extends to three equations in three variables, demonstrating how to model and solve more complex problems involving tickets, drinks, and popcorn. The elimination method is used to find the solution, and the tutorial concludes with a discussion on the unique solution of the system and a preview of future topics involving non-linear equations.

Explain how the elimination method works in solving systems of equations.
