Solving Two-Step Inequalities in Algebra

The video tutorial explains how to solve an inequality involving fractions and mixed numbers. It begins by converting mixed numbers to improper fractions, then eliminates fractions by multiplying both sides of the inequality. The tutorial continues by simplifying the inequality and isolating the variable y. Finally, it interprets the solution and demonstrates how to represent it on a number line.

What is the first step in solving the inequality 2/3 > -4y - 8 1/3?

• Add 8 1/3 to both sides

• Multiply both sides by 3

• Convert 8 1/3 to an improper fraction

• Subtract 2/3 from both sides

What is 8 1/3 converted to an improper fraction?

• 25/3

• 27/3

• 26/3

• 24/3

Why do we multiply both sides of the inequality by 3?

• To swap the inequality sign

• To make the inequality simpler

• To eliminate the fractions

• To isolate the variable
