bonjour
x = 3 790 + x /4 + x /2
4 x /4 = 15 160 + x /4 + 2 x /4
4 x - x - 2 x = 15 160
x = 15 160
le véhicule vaut 15 160 €
il emprunte la moitié = 15 160 : 2 = 7 580 €
x = 2 x /5 + x /5 + 8 + 16
5 x /5 = 2 x /5 + x /5 + 40/5 + 80/5
5 x - 2 x - x = 40 + 80
2 x = 120
x = 60
il y a 60 appartements
premier = 60 x 2/5 = 24
second = 60 x 1/5 + 8 = 12 + 8 = 20
dernier = 60 - 44 = 16
