 -----------------------------------(1)
                          -----------------------------------(1)
 --------------------------------(2)
                    --------------------------------(2)
Now, substituting the value of x from equation 2 in equation 1,
 
 





 ------------------------(3)
          ------------------------(3)
Now, substituting the value of y from equation 3 in equation 2,

 ------------(from equation 3)
       ------------(from equation 3)

 ----------------------(4)
              ----------------------(4)
As, x is price of 1 child ticket and y is price of 1 adult ticket,
Therefore price of 1 child ticket is $5.4 and price of 1 adult ticket is $10.8
