9ax + 9b − 6 = 21
Based on the equation above, what is the value of ax + b ?

A

3

B

6

C

8

D

12

Text Solution

Verified by Experts

The correct Answer is:
A
To isolate the terms that contain ax and b, 6 can be added to both sides of the equation, which gives 9ax + 9b = 27. Then, both sides of this equation can be divided by 9, which gives ax + b = 3. Choices B, C, and D are incorrect and may result from computation errors.
