Average movie prices int he United states are, in general, lower than in other countries. It would cost $79.663 to buy three tickets in Japan plus two tickets in Switzerland. Three  tickets in Swizterland plus two tickets in Japan would cost $75.57. How much does an average movie ticket cost in each of these countries?

Let  J  represent the number of tickets in Japan.

Let  S  represent the number of tickets in Switzerland.

I'm going to modify the $79.663 to $79.63:

3J + 2S  =  79.63    --->     3J + 2S  =  79.63   (multiply by 2)  --->   6J + 4S  =    159.26

3S + 2J  =  75.57     --->     2J + 3S  =  75.57    (multiply by -3) -->  -6J  - 9S  =  -226.71  

                                                       Add down the columns:                    -5S  =  -67.45

                                                                                                                S  =  $13.49

When  S = 13.49 --->   3J + 2(13.49)  =  79.63   --->  3J + 26.98  =  79.63   --->  J  =  $17.55
