3 unknown functions, but only 2 equations

Now you have three unknown functions, X(x), R(x), and T(x), but only two equations. We need more information about T(x) in order to solve or plot this.

yeah thats what i thought it is so frustrating

yeah thats what i thought it is so frustrating i am just trying to plot some graphs grrrr.

If T(x)=R^1/4(x)/x, would that be enough?

Should be enough, with correct initial conditions

That definition of T(x) should be enough. But your initial conditions are ill-posed:

R(x) = 0, X(x) = 10;

Shall I assume that that should be
R(0) = 0, X(0) = 10
?
