Understanding Solutions in Linear Equations

This video tutorial explores solving linear systems, focusing on cases with no solutions. It covers three possibilities: parallel lines with no solutions, intersecting lines with one solution, and coinciding lines with infinite solutions. An example problem is solved to demonstrate a system with no solution, emphasizing the importance of understanding when lines do not meet.
