Math Problem Statement

-4b - 9 > -5

Solution

Let's solve the inequality step by step. The inequality in the image is:

4b9>5-4b - 9 > -5

Step 1: Simplify the inequality

Add 9 to both sides to isolate the term with bb: 4b9+9>5+9-4b - 9 + 9 > -5 + 9 4b>4-4b > 4

Step 2: Solve for bb

Divide both sides by 4-4. Remember, dividing or multiplying an inequality by a negative number reverses the inequality sign: b<44b < \frac{4}{-4} b<1b < -1

Final Answer:

b<1b < -1
