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
