Explicație pas cu pas:
a + b + c = 232
a : b = 14 rest 5
b : c = 7 rest 1
a = b • 14 + 5
b = c • 7 + 1
b = 7c + 1
a =(7c + 1) • 14 + 5
a = 98c + 14 + 5
98c + 14 + 5 + 7c + 1 + c = 232
106c =232 - 14 - 5 - 1
106c = 212
c = 212 : 106
c = 2
b = 2 • 7 + 1
b = 14 + 1
b = 15
a = 98 • 2 + 14 + 5
a = 196 + 14 + 5
a = 215
215 + 15 + 2 = 232
230 + 2 = 232
232 = 232
