If you want to solve this equation for x, then you have the following two methods to do it in MATLAB.
1) If you have symbolic toolbox
syms x
eq = 30*x-11 == 30/x;
sol = solve(eq);
2) Your equation is a polynomial (for ). You can use roots()
% polynomial is 30x^2-11x-30=0
cf = [30 -11 -30];
sol = roots(cf);
