9ax+9b-6=21

Question

what is the value of ax+b

Answer 1

9(ax + b) - 6 = 21 if we pull out the common factor of 9 from the first two terms

 

9(ax + b) = 27 if we add 6 to both sides

 

ax + b = 3 when we divide both sides by 3

Answer 2

In an Algebra class, you can learn the following:

1.  Add 6 to each side

2. Divide everything by 9.

 

If you do so, you will have the answer to your question.
