Q1. Solve the following inequality. Graph the solution set and write it in interval notation:

Background

Topic: Linear Inequalities

This question tests your ability to solve linear inequalities in one variable, graph the solution on a number line, and express the solution in interval notation. These are foundational skills in intermediate algebra.

Key Terms and Formulas

• Inequality: A mathematical statement that compares two expressions using symbols such as , , , or .

• Interval Notation: A way to describe the set of solutions to an inequality using parentheses and brackets.

• Addition Property of Inequality: You can add (or subtract) the same value from both sides of an inequality without changing its direction.

Step-by-Step Guidance

1. Start by writing the inequality:

2. Subtract from both sides to get all terms on one side:

3. Combine like terms to simplify both sides:

4. Add $13xx - 13 + 13 < -8 + 13$

5. Simplify the right side to get by itself. (Pause here before the final calculation!)
