20. The sum of Gerald’s age and Fred is 53. Five years ago, Gerald was 7 years more than onehalf as old as Fred. What are their current ages?

algebra 
Steve,
If the current ages are f and g,
f+g=53
(g5) = (f5)/2+7
2(53f5) = f5 + 14
f = 29
g = 24
check:
5 years ago, Fred was 24 and Gerald was 19
195 = (295)/2+7
14 = 14
