let x=adults' tickets
    y=children's tickets
   
   x+y=500         
   y=500-x

perform the indicated operations in the equation:

   4.50x+2.50(500-x) =1650
   4.50x+1250-2.50x =1650
   4.50x-2.50x =1650-1250
   2x/2= 400/2
    x=200 adults' tickets

   y=500-200
   y=300 children's tickets

since, 200x4.50 =900
       300x2.50 =750
        900+750 =1650 ticket sales
