Your problem description is faulty. Either x is a constant or it is variable. x cannot be both constant and variable in the same equation. I am solving an adjusted problem.

This is the adjusted problem.
Given that y is proportional to (16-x) and the constant of proportionality is equal to r. Find the value of x when y is 1.

y=r%2816-x%29
You still were given no information to allow finding a value for the proportionality constant.

Let y=1, find x or r?

r=1%2F%2816-x%29
or 1%2Fr=-x%2B16

The question is not any further resolvable.
x=16-1%2Fr


FURTHER: If the variation is "varies inversely", the problem still has the same fault and the description and question are still wrong. x cannot be both an input variable and a proportionality constant in the same problem, exercise, or equation.
