Solving Two Step Inequalities Challenge

This video tutorial explains how to solve two-step inequalities, highlighting the differences from solving equations, such as using inequality symbols instead of equal signs and having a set of solutions. It covers the rule of flipping the inequality symbol when multiplying or dividing by a negative number. The video provides three examples, demonstrating how to solve and graph inequalities on a number line, emphasizing the importance of open and closed circles to represent solutions.

What is the main difference between solving equations and solving inequalities?

• Equations use inequality symbols.

• Inequalities are always more complex than equations.

• Equations always have more than one solution.

• Inequalities use different symbols and can have multiple solutions.

What happens to the inequality symbol when you multiply or divide by a negative number?

• It stays the same.

• It flips to the opposite direction.

• It becomes an equal sign.

• It disappears.
