Question 756752
let j = cost of a ticket in Japan
let s = cost of one in Switzerland
:
Write an equation for each statement:
:
 It would cost $79.21 to buy three tickets in japan 
 plus two tickets in switzerland.
3j + 2s = 79.21
: 
 Three tickets in switzerland plus two tickets in japan would
 cost $75.39.
2j + 3s = 75.39
:
Use elimination here multiply the 1st equation by 3, the 2nd eq by 2
9j + 6s = 237.63
4j + 6s = 150.78
-----------------subtracting eliminates s, find j
5j = 86.85
j = 86.85/5
j = $17.37 per ticket in Japan
:
Use the first equation to find s, replace j with 17.37:
3(17.37) + 2s = 79.21
52.11 + 2s = 79.21
2s = 79.21 - 52.11
2s = 27.10
s = 27.10/2
s = $13.55 in Switzerland
:
:
You can confirm this yourself, do the math in the 2nd equation
2(17.37) + 3(13.55) = 75.39
