If x is a constant, (i.e. x(2)=x×2 )  then the solution is:  x(2)=((4(√7)−2(√5))/( (√7)+(√5)))    But I′m guessing x is here a function...  in that case, your question has no solution  unless you give constraints on “the kind of  function” that you are looking for.  (to be precise there are infinutely many  solutions, so much so that you can′t describe  them all)
