Question

Your dog is 8 years younger than your friend. In 2 years, your friend will be three times as old as your dog. How old is your dog now?

Answer 1

Answer:

5 years old

Step-by-step explanation:

let 'f' = age of friend

let 'f+2' = age of friend in 2 years

let 'f-8' = age of dog now

f + 2 = 3(f - 8)

f + 2 = 3f - 24

-2f = -26

f = 13

currently, friend is 13 and dog is 5
