Orly's age is 4 years more than thrice Perla's age. Four years ago, Orly was four times as old as Perla was then. How old is each now?

  • math -

    Present age:
    Perla --- x
    Orly ---- 3x+4

    four yrs ago
    perla -- x-4
    orly ---- 3x+4 - 4 or 3x

    "Four years ago, Orly was four times as old as Perla was then"
    ---> 3x = 4(x-4)
    3x = 4x - 16
    x = 16
    So Perla is 16 and Orla is 52

    check:
    now: Perla = 16, Orla = 52
    4 yrs ago : Perla = 12, Orla = 48
    Is 48 four times 12 ? YEA

    Reiny i have some question if Perla is x=16 how about the solution for Orly

  • math -
