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?

1 answer

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~ :)
