* *let the age of jim be x carla's age= x+5 tomy's age= 6+5+x sum of their ages=31 x+x+5+x+5+6=3x+16=31 3x=31-16 =15 x=15 divided by 3 = 5 jim's age=5 carla's age= 10 tomy's ag e = 16
x - Jim y - Carla z - Tomy
y = x + 5 z = y + 6 x + y + z = 31 x = y − 5 z = y + 6 x + y + z = 31 y − 5 + y + y + 6 = 31 3 y = 30 y = 10 x = 10 − 5 x = 5 z = 10 + 6 z = 16
Jim is 5 years old, Carla is 10 years old, and Tomy is 16 years old. We calculated their ages by setting equations based on the age relationships and the total sum of their ages. The calculations show the steps clearly, leading to the correct ages for each family member.
