MsPJ,
You need to know how many total tickets were sold. The only thing you can do with this is s(adult tickets)+2s(student tickets)=t(total tickets)

joey,
oh, it didn't post the whole thing...
A total of 321 tickets were sold for the school play. The number of student tickets sold was two times the number of adult tickets sold. How many tickets were sold?

Hunter,
Joey, divide the total of 321 by 3. that's the number of adult tickets. double that answer and that's the number of student tickets.
