I get 6

 

(-15)  is a  multiple  of 15

 

(21)  is a multiple  of 21

 

So

 

-15  + 21  =  

 

6

 

Anyone  have a different (better) answer   ???

How about: -7(15) + 5(21) = 0

That doesn't work becuase the question asks for "What is the smallest positive integer..." and 0 is not positive.

 

Hope it helps!
