.

    72 +  +  = x.


You do the rest.


Your goal is to find x, the total number of the T-shirts.


To do it, multiply both sides by 9 and simplify.

Let x be the original number of t-shirts.

72 were sold, leaving (x-72)
4/9 of those (x-72) were then sold
1/3 of the original x remained

The total number sold, plus the number remaining, equals the original total:






The original number of t-shirts was 180
72 were sold, leaving 108
4/9 of those 108, or 48, were sold, leaving 60, which is 1/3 of the original number.

ANSWER: The total number sold was 72+48=120
