Question 638111

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(2y - 4)}}} years-old


Since y = 8, then Janice's age = 2(8) - 4, or 16 - 4, or {{{highlight_green(12)}}}


Since y = 8, then Christina's age = 2(8), or {{{highlight_green(16)}}}
