A movie theater has 400 seats. Tickets at the theater cost $8 for students, $10 for adults, and $7 for senior citizens. On a night when all the seats were sold, the theater made $3,535 from ticket sales. If the number of adult tickets sold was 10 less than the number of student and senior tickets combined, how many senior tickets were sold?

If there are s students, a adults, and g geezers, then

s+a+g = 400

8s+10a+7g = 3535

a = s+g-10

Now just solve for the numbers
