You can put this solution on YOUR website!
Let +a+ = number of adult tickets sold
Let +s+ = number of student tickets sold
--------------
(1) +a+%2B+s+=+553+
(2) +s+=+a+%2B+53+
------------------
Substitute (2) into (1)
(1) +a+%2B+a+%2B+53+=+553+
(1) +2a+=+553+-+53+
(1) +2a+=+500+
(1) +a+=+250+
250 adult tickets were sold
