7 x + 2
-- ----
24 = 12


x over 3 = 224 over 720

  • Math problems -

    GOAL: Isolate the variable (x)

    Multiply both sides by 24.

    7x + 2 = 288

    Subtract 2 fromboth sides.

    7x = 286

    Divide both sides by 7.

    x = 40.9


    The next question is the same, but instead you can just cross multiply.

    x/3 = 224/720

    720x = (224)(3)

    720x = 672

    x = 0.93

  • Math problems -

    I read that as
    7/24 = (x+2)/12

    if so, then

    24x + 48 = 84
    24x = 36
    x = 36/24 = 3/2
