Bettina’s age is three times Melvina’s. If 20 is added to Melvina’s age and 20 is subtracted from Bettina’s age, their ages will be equal. How old is each now?

Question

Pls help on my rsm homework, it's like impossible.

Answer 1

Hi Rose,

if we let x = Melvina’s age

and 3x = Bettina’s age

our equation is

x+ 20 = 3x -20

solve and x = 20

3x = 60

I hope this helps
