To solve this problem you must apply the proccedure shown below:
1. You have:
x: the positive integer that is twice another.
y: the other positive integer.
2. Therefore, you must write a system of equations, as following:
x=2y
(1/y)-/(1/x)=1/8
3. By susbtitution, you obtain:
(1/y)-/(1/2y)=1/8
y=4
x=2x4
x=8
The answer is: 8 and 4.
