Respuesta :
Kim= 2* Tim
Tim= 5+Jim
Kim+ Tim+ Jim=75
2 Tim + (5 +Jim)+ Jim =75
2 (5 +Jim) + 5+ Jim + Jim= 75
10+ 2 Jim + 5+ Jim+ Jim= 75
4 Jim = 75- 10- 5= 60
Jim =15
Tim= 5+ 15= 20
Kim= 2* 20= 40
Kim= 2* Tim
Tim= 5+Jim
Kim+ Tim+ Jim=75
2 Tim + (5 +Jim)+ Jim =75
2 (5 +Jim) + 5+ Jim + Jim= 75
10+ 2 Jim + 5+ Jim+ Jim= 75
4 Jim = 75- 10- 5= 60
Jim =15
Tim= 5+ 15= 20
Kim= 2* 20= 40
