Average movie prices in the United States are, in general, lower than in other countries. It would cost $79.38 to buy three tickets in Japan plus two tickets in Switzerland. Three tickets in Switzerland plus two tickets in Japan would cost $75.12 How much does an average movie ticket cost in each of these countries?

3j + 2s = 79.38

3s + 2j = 75.12. 3s + 2j - 3s = - 3s + 75.12. 2j/2 = - 3/2s + 75.12/2.

j = - 1.5s + 37.56

Then you can use substitution

3 (-1.5s + 37.56) + 2s = 79.38

-4.5s + 112.68 + 2s = 79.38

-2.5s + 112.68 - 112.68 = 79.38 - 112.68

-2.5s = - 33.30

-2.5s/-2.5 = - 33.30/-2.5

s = 13.32

So s is 13.32 so you plug that back in and solve for j

3j + 26.64 = 79.38

3j + 26.64 - 26.64 = 79.38 - 26.64

3j = 52.74

3j/3 = 52.74/3

j = 17.58

So in Japan tickets average 17.58 and in Switzerland they average 13.32
