four times the difference or two posotive integer numbers is equal to half the sum of the numbers. If one of the numbers is 14, what is the other number?
I just cant get this can anyone help me?

  • Math -

    let x = the other number
    then we set-up the equation.
    4*(x-14) = (1/2)*(x+14)
    4x - 56 = (1/2)x + 7
    4x - 0.5x = 56 + 7
    3.5x = 63
    x = 18

    hope this helps~ :)
