Hi

I need help resolving x from this equation. So that I end up with an equation like x = ...

y=sine(x*pi)/(x*pi)

The equation is used in FFT analysis, describing the amplitude of the leakage.

I doubt that the inverse of the sinc function can be expressed as a composition of conventional functions like root and trigonometric functions. It can be approximated by polynomials. See here.
