Hello and welcome to FMH! 
I've moved and re-titled the thread since this problem has nothing to do with calculus/differential equations. Which of the following is correct?
[MATH]f(x)=\frac{x-3}{2x}[/MATH]
[MATH]f(x)=x-\frac{3}{2x}[/MATH]
[MATH]f(x)=x-\frac{3}{2}x[/MATH]

1st you need to tell us which of the functions MarkFL stated is correct. Then replace x with (x+1), then replace x with (2x), then subtract, then set this result equal to 0.5 and finally solve for x.
