James is three times as old as Mattie. Jazmin is 3 years younger than Mattie. The sum of their ages is 62. How old is each person?

Answer 1

J=3M

Z=M-3

J+M +Z = 62

3M +M + M-3 = 62

5M =62+3 =65

M =65/5 = 13 years old for Mattie

James =3(13) = 39 years old

Jazmine =13-3 = 10 years old

13+39+10 =62
