For inequalities involving rational expressions, you can try:
(%i6) load("solve_rat_ineq.mac")$
(%i7) solve_rat_ineq((x+5)*(x-9) >= 0);
(%o7) [[x<=-5],[x>=9]]
(%i8) solve_rat_ineq((x+5) /(x-9) >= 4);
(%o8) [[x>9,x<=41/3]]
(%i10) solve_rat_ineq((x+5)*(x-13)/(x-9) >= 4);
(%o10) [[x>=6-sqrt(65),x<9],[x>=sqrt(65)+6]]
