OpenStudy (anonymous):

@AnswerMyQuestions @Michele_Laino do you wantme to type it or can you zoom in?

OpenStudy (michele_laino):

please note that if I call with "j" the cost of tickets in Japan, and with "s" the cost of tocket in Switzerland, then your exercise can be mathematized by the subsequent system: \[3j+2s=77.72, 2j+3s=73.63\] so, please solve that system for j and for s

OpenStudy (michele_laino):

oops...of tickets in Switzerland...

OpenStudy (anonymous):
