Melissa is 24 years younger than Joyce. In 2 years, Joyce will be 3 times as old as Melissa will be then. How old are they now?

Question

Please help

Answer 1

Joyce = J years old

Melissa = J - 24

 

J + 2 = 3(M + 2)

J + 2 = 3(J - 24 + 2)

J + 2 = 3J - 66

2J = 68

J = 34

J - 24 = 34 - 24 = 10 (Melissa)

 

So Joyce = 34 years

Melissa = 10 years
