not eliminating parameter

Eliminate[ { x /c == Coth[x/c], y/c == Cosh[x/c]}, c ] It was expected with the first relation that x/c would be iterated in a FindRoot / NSolve mode to get a solution, say x/c = u, c = x/u leading to y/x = Cosh[u]/u by insertion into the second equation. But but there are no solutions, several &&s appear. I could have done the first one manually, but is there some automatic way out? Thanks for indication. Narasimham
