Finn is 9 years younger than Pari. Pari is twice as old as Finn. How old is Finn?

Answer 1

Finn = 9
Pari = 18

9+9=18
18 / 2 = 9

Answer 2

Eli, if this were a 4 mark question on my test, I would give you 1 mark for the answer.

proper method:

let Pari's age be x
then Finn's age is x-9

x = 2(x-9)
x = 2x - 18
-x = -18
x = 18

So Pari is 18, and Finn is 9
