Solving Two Step Inequalities Challenge

The video tutorial introduces students to solving two-step inequalities, similar to solving two-step equations but with additional graphing and sign-flipping rules. It outlines the steps to solve these inequalities, including undoing addition/subtraction and multiplication/division, and provides multiple examples to illustrate the process. The tutorial emphasizes the importance of flipping the inequality sign when multiplying or dividing by a negative number and encourages students to practice independently.

What is the first step in solving a two-step inequality?

• Undo the multiplication or division

• Graph the solution

• Undo the addition or subtraction

• Flip the inequality sign
