Juan + Santiago + Andres = $ 540
Juan = 2.(Andres)
Santiago = Juan - $40
Juan + Santiago + Andres = $ 540
2.Andres + (Juan -$40) + Andres = $540
2.Andres + 2.Andres - $ 40 + Andres = $ 540
5Andres = $540 + $40
Andres = $580 / 5
Andres = $ 116

Juan = 2.Andres → Juan = 2.$116 →Juan = $232

Santiago = Juan - $40 → Santiago = $232 - $40 → Santiago = $192

entonces
Juan = $232          Andres = $116             Santiago= $ 192

espero que te sirva, salu2!!!!
