.
Let x = # of tickets sold at $50.


Then the number of tickets sold at $20 was 3x, according to the condition,

and the rest, (5000-x-3x) were sold at $30.


Therefore, your "money" equation is

50x + 20*(3x) + 30*(5000-x-3x) = 140000   dollars total  (the revenue !).


50x + 60x + 150000 - 120x = 140000

-10x = 140000 - 150000 = -10000

x =  = 1000.


Answer.  1000 tickets at $50;  3000 tickets at $20  and  1000 tickets at $30.
