Linear Equations and School Cooperative Problem

The video tutorial introduces a problem involving a system of linear equations with three variables. It describes a scenario at a school cooperative where Arya, Bilqis, and Citra make purchases without knowing the individual prices of items. The problem is to determine if Rara has enough money to buy the same items. This scenario serves as a basis for discussing and solving linear equations.
