Solving Systems of Equations in Real-World Scenarios

The video tutorial covers solving systems of equations using a real-world problem involving camera rentals. The teacher explains the setup, defines variables, formulates equations, and graphs them to analyze costs. The substitution method is also demonstrated for solving equations. The tutorial concludes with a summary and an assignment for the next class.
