x=adults
y=children

Finding the y value: -5(6x+15y=$423)---> -30x-25y=-215
                                6(5x+9y=$293)---->.    30x-54y=1758 
(cross out -30x and 30 because.             ------------------
                                                                     -21y=357 and y=17
they are like terms)


Finding the x:
6x+15(17)=423
6x+225=423
6x=168
x=28

So y=17
      x=28
