solve an equation to find a point

Dear all,

I have solved the below system of PDEs

u"(x)+u'(x)=f(x)
v"(x)+v'(x)=g(x)

And this equation is solved. Now in each solved time step, for each point like (x), I'd like to find a point (y) which satisfies:

x+u(x)=v(y)+y

This is just an example though, suppose that I am sure of the uniqueness of that point. Any idea how to incorporate this?

I appreciate any help,
Thank you,
Hossein
