~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

At a given condition, there are many solutions, and you can not select a unique solution.

The equation for this situation is

2c + 1.5r = 135. (c is the length of chains in feet, r is the leng of ropes).

You have one equation for 2 unknowns.

In order for to have the unique solution, you need one more equation.
It means that the condition should include one more restriction.
