There are 540 students at a walk-in clinic, each
of which has either the flu, a sinus infection, or bronchitis (no student has more than one of these illnesses). If the number of students
with the flu is two times the number of students with bronchitis, and
the number of students with a sinus infection is three times the number of students with the flu, how many of the 540 students have the flu?
