60, how old is the youngest of them?
​

Answer 1

Paul is the youngest at 17 years old. Fiona is 20 years old, Sara is 23 years old

Explanation:

Assign variables to the ages.

S = sara's age

F = Fiona's age

P = Paul's age.

S + F + P = 60

S = 3 + F

P = F - 3

(3 + F) + F + (F - 3) = 60

3 + 3F - 3 = 60

3F = 60

F = 20

S = 23

P = 17
