Question

4. Solve the following inequality for b, showing all of your work carefully and completely

4b - 12 - 55 < 9b +8​

Answer 1

b > -15

Explanation:

4b - 12 - 55 < 9b + 8

Combine terms.

4b - 67 < 9b + 8

Subtract 9b from both sides.

-5b - 67 < 8

Add 67 to both sides.

-5b < 75

Divide both sides by -5. When dividing by a negative, flip the sign.

b > -15.
