Or, if you prefer, I replaced sqrt(x) by u and sqrt(y) by v, found the values of u an v (by inspection - i.e. guesswork!), then squared the resulting values to get x and y.

In these types of equations, there is no DIRECT solution, but iteration and interpolation methods are used, such as Newton-Raphson method. It is basically "trial and error" method.
