You can put this solution on YOUR website! "Six years ago,... is,..."
No. Either drop the six years ago, or say "was".
This part: "Six years ago,Mac's age is 20 years less than twice Kim's age. "
seems to say how the first portion relates to Kim's age NOW.
IF Kim is 3 years older (NOW), then 
-
   ----------their ages now.
In four years, Mac and Kim, 12 and 15.
Maybe problem is really supposed to be this way:
=======================================================================
Six years ago, Mac's age was 20 years less than twice Kim's age. If Kim is 3 years older than Mac's,...
=======================================================================
 ----------then substitute for 
 --------
Their ages in four more years,
=============
Mac, 24
Kim, 27
=============
