Janet is three years older than her sister Julie.Janets brother is 8 years younger Than Her sister Julie .the sum of all of their ages is 55 years

Respuesta :

x + x + 3 + x - 8

3x - 5 = 55

3x = 60, x = 20

Since we put Julie as x, we put Janet at x + 3, and the brother is x - 8 (8 years younger)

Julie is 20

Janet (x + 3) = (20 + 3) = 23

Brother(x - 8) = (20 - 8) = 12
