*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \sqrt{110\ -\ n}\ =\ n]


Square both sides:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 110\ -\ n\ =\ n^2]


Collect all terms on the left:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ n^2\ +\ n\ -\ 110\ =\ 0]


Solve the factorable quadratic equation.  Hint:  -10 + 11 = 1 and -10 X 11 = -110.  Remember to check your solutions in the original equation.
