if x, y, and z are positive numbers, with xy = 24, xz = 48, and yz = 72, what is x + y + x? please explain how you got tha answer too. thank you.

  • Algebra -

    xz = 48
    yz = 72

    xy = 24

    x = 4, y = 6, z = 12

    x + y + z = 4 + 6 + 12 = 22

    I did this manually, by trial an error

    there must be an easier way ?

    I am not a tutor
    maybe a tutor will answer with an easier way
