Carla is 5 years old and Jim is 13 years younger than Peter. One year ago Peter's age was twice the sum of Carla and Jim's age. Find the present age of each of them
Carla = 5 years old Jim = 2 years old Peter = 15 years old (Peter was 14 years old one year ago) 5+2=7 7x2=14 (14 is the age from one year ago meaning 15 is the current age) 15-2=13
