Price of movie ticket in Japan is x=7.362$

Price of movie ticket in Switzerland is y=13.652$

Step-by-step explanation:

Let, Price of movie ticket in Japan is x

Price of movie ticket in Switzerland is y

Statement 1 : Total of 79.39$ of three movie ticket in Japan and two movie ticket in Switzerland

We write, 3x+2y=79.39        ( Equation 1 )

Statement 1 : Total of 75.68$ of two movie ticket in Japan and three movie ticket in Switzerland

We write, 2x+3y=75.68        ( Equation 2 )

Solving by method of elimination

Multiplying equation 1 by 2, we get

6x+4y=158.78

Multiplying equation 2 by 3, we get

6x+9y=227.04

Subtracting both the linear equation,

  6x+4y=158.78

- 6x+9y=227.04

_______________

 0x-5y=(158.78-227.04)

-5y=(-68.26)

5y=68.26

y=13.652$

Replacing value of y in any equation

3x+2y=79.39

3x+2(13.652 )=79.39

x=17.362$

Thus,

Price of movie ticket in Japan is x=7.362$

Price of movie ticket in Switzerland is y=13.652$
