Number of Adults Ticket=393
Number Of Students Tickets=792
Step-by-step explanation:
Let 'x' be the Adult's tickets
Let 'y' be the Student's tickets
x+y=1185 (total sold tickets)
5x+y=2757(total cost of tickets)
-(5x+y=2757)x+y=1185
(-5x-y)- x+y=1185-2757
=-4x+0 = (-1572)
=-4x=(-1572)
x= (-1572)÷-4
=393
=x+y=1185
=393+y=1185
=y=792
So Number of Adults Ticket=393
Number Of Students Tickets=792
