a+b+c = 232
a:b = 14 rest 5 ==> a = 14×b+5
b:c = 7 rest 1 ==> b = 7×c+1
a = 14×(7×c+1) + 5 = 98×c+14+5 = 98×c+19
inlocuim in prima relatie in functie de c
98×c+19 + 7×c+1 + c = 232
106×c = 232 - 20 = 212
c = 212 : 106 = 2
b = 7×2+1 = 15
a = 98×2+19 = 196+19 = 215
a = 215
b = 15
c = 2
Verificare:
215+15+2 = 232
215 : 15 = 14 rest 5
15 : 2 = 7 rest 1
