Solving Multi-Step Equations and Inequalities

This video tutorial by Mr. Richards covers solving multi-step equations and inequalities, including distribution, identities, and equations with no solutions. It also explores solving and checking multi-step inequalities and applying them to real-world scenarios. The lesson concludes with graphing solutions on a number line.
