 Question 302164: Pamela is 9 years older than Jiri. The sum of their ages is 107 . What is Jiri's age? Answer by london maths tutor(243)   (Show Source): You can put this solution on YOUR website!Let's Jiri's age be "J" and Pamela's age be "P". P = 9 + J (Pamela is 9 years older than Jiri) ... equation 1 P + J = 107 (the sum of their ages is 107) ... equation 2 Put equation 1 into equation 2: (9+J) + J = 109 9 + 2J = 109 2J = 109 - 9 2J = 100 J = 100/2 J = 50 Therefore,Jiri's age is 50.
