Solving Multi-Step Inequalities in Algebra

This lesson covers solving multi-step inequalities, including those involving the distributive property. It provides examples such as a financial literacy problem, converting verbal expressions to inequalities, and handling parentheses. The lesson emphasizes understanding and solving inequalities through various examples, ensuring students can apply these skills independently.

What is the main focus of lesson five?

• Understanding quadratic functions

• Graphing linear equations

• Solving multi-step inequalities

• Solving single-step equations
