Question 184768: molly is 4 years younger than heidi. in 3 years heidi will be twice as old as molly. How old are they now?
Answer by hustla7(3)   (Show Source):
You can put this solution on YOUR website! Molly is 1, Heidi is currently 5
In 3 years, molly will be 4, heidi 8, thus the condition is met....wasy peasy, bit of trial and error, starting with an educated guess, as you know that these 'doubles' are only likely to work with small numbers
