Fred is four years older than barney. five years ago the sum of their ages was 48. how old are they nw

Fred is 31 and Barney is 27.

If the sum of their ages was 48 and Fred was 4 years older, you subtract 4 from 48 to get 44. Then you divide 44 by 2 and get 22 for each age. You add the 4 back to Fred's age and then add 5 years to both 26 and 22 to get 31 and 27.
