Christina is twice as old as Melissa. Janice is 4 years younger than Christina. If Melissa is y years old, how old is Janice? Find Janice's age and Christina age when y=8. I got stumped and hope this equation is right 2(y+4) Please help. Thanks

Since Melissa is y years-old, then Christina's age = 2y

Janice is highlight_green%282y+-+4%29 years-old

Since y = 8, then Janice's age = 2(8) - 4, or 16 - 4, or highlight_green%2812%29

Since y = 8, then Christina's age = 2(8), or highlight_green%2816%29
