Solving Two Step Inequalities in 7th Grade Math

The video tutorial covers solving two-step inequalities, emphasizing the use of inverse operations and the importance of reversing the inequality symbol when dividing or multiplying by a negative number. It includes examples of solving inequalities, checking solutions, and graphing results. The tutorial also explains how to determine if a given value satisfies an inequality and concludes with a summary of key points.

What is the main objective when solving two-step inequalities?

• To find the exact value of the variable
