Solving Multistep Inequalities Challenge

The video tutorial covers solving multi-step inequalities, similar to solving two-step equations, with a focus on handling the inequality sign. It explains the process of distributing, combining like terms, and solving for the variable. The tutorial also includes graphing solutions on a number line and provides examples, including those with negative numbers, to reinforce understanding. The video concludes with practice problems for students to solve.

What is the first step in solving multi-step inequalities?

• Draw railroad tracks around the inequality sign

• Distribute if needed

• Combine like terms

• Circle the variable
