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?

Question

I just cant get this can anyone help me?

Answer 1

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~ :)
