Learn the easy way to solving and graphing a multi step inequality with variables on both

The video tutorial explains how to solve and graph inequalities. It begins by highlighting the differences between solving equations and inequalities, particularly the need to reverse the inequality symbol when multiplying or dividing by a negative number. The instructor then demonstrates solving a specific inequality step-by-step, ensuring the variable is isolated on one side. Finally, the solution is graphed on a number line, showing how to determine the solution set and shade the appropriate region.
