Let s=students, and a=adults
For total tickets sold:
s+a=937
For total money sales:
3s+5a=3943
Multiply tickets sold by 3 to eliminate the student variable from the system of equations to get
(3s+5a=3943)-(3s+3a=2811)
or
2a=1132
a=566=the number of adult tickets sold
s=937-566=371 = the number of student tickets sold.
