Math Help - Making n the subject in this equation.

Hi this is my first thread so i hope i have the right forum, ive been trying to make n the subject in the equaion

Z = X-2n/Sqrt nt^2 + nt^2

the squareroot goes over the entire bottom part of the fraction, and t stands for symbol theta (not sure how to get greek characters) and the reason why there are 2 of the nt^2 is because theta is subscripted a and b.

if anyone couls shed any light on this it would be a big help!!

thanks

ques is not clear,,,,,where are "a" and "b"

the subscripts are bottom right of t
