This video tutorial introduces solving inequalities involving one variable. It covers the basics of inequalities, how to graph them on a number line, and the differences between solving equations and inequalities. The tutorial provides examples of simple inequalities and explains the importance of flipping the inequality sign when multiplying or dividing by a negative number. It concludes with more complex examples to ensure comprehensive understanding.

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

• You cannot graph inequalities.

• Inequalities involve a range of solutions instead of a single solution.

• You use different mathematical operations for inequalities.

• The variable is always on the left side in inequalities.

What must you do when you divide or multiply both sides of an inequality by a negative number?

• Keep the inequality sign the same.

• Subtract the same number from both sides.

• Flip the direction of the inequality sign.

• Add the same number to both sides.
