Exploring Systems of Equations in Algebra

This video tutorial explores systems of linear equations through a practical comparison of electric and gas cars. It examines the cost and environmental impact of both vehicle types over a 12-year period. The lesson includes constructing linear equations to model costs, using graphs to find break-even points, and analyzing emissions data to determine environmental benefits. The tutorial also discusses the implications of electric car production and energy sources on their overall sustainability.
