Kit is twice as old as his friend Sam. Sam is 5 years older than Cara. In 5 years, Kit will be three times as old as Carla. How old is Sam?

Sagot :

Carla's age: x
Sam: x + 5
Kit: 2(x+5) or 2x + 10

In 5 years (Add 5):
Carla's age: x + 5
Kit: 2x + 10 + 5 or 2x + 15

Equation:
3 (x+5) = 2x + 15
3x + 15 = 2x + 15
3x - 2x = 15 - 15
x = 0

Their ages:
Carla: 0 (could be an infant)
Sam is 5 year old
Kit is 10 years old
