<h3>What is this algebra about?</h3>
Note that:
A total of 378 tickets were sold for the school play.
So:
A + S = 378
S = 2A
A + (2A) = 378
3A = 378
A = 126
If A is 126, then S is double of that, or 252.
126 + 252 = 278
Therefore, Since there were 72 fewer students tickets sold than adults tickets. the number of adult tickets that were sold is 278.
