Understanding Systems of Inequalities

The tutorial explores systems of inequalities, comparing them to linear equations. It covers graphing and solving systems with examples, including basic inequalities, linear inequalities, and those involving absolute values. The tutorial concludes with a complex system of three inequalities, emphasizing the importance of finding overlapping regions as solutions.
