Question 1128530
let j be the cost of a ticket in Japan and s be the cost of a ticket in Switzerland, then
:
1)  3j +2s = 79.46
:
2)  2j +3s = 75.89
:
multiply equation 1 by 2
:
3)  6j +4s = 158.92
:
multiply equation 2 by 3
:
4)  6j +9s = 227.67
:
subtract equation 3 from equation 4
:
5s = 68.75
:
s = 13.75
:
subtract equation 2 from equation 1
:
j -s = 3.57
:
j = s +3.57
:
substitute for s
:
j = 13.75 +3.57 = 17.32
:

:
79.46 = 79.46
:
equation 2
:
2(17.32) +3(13.75) = 75.89
