Explicație pas cu pas:
3a..........7b...............1222 (x 4)
4a..........6b...............1186 (x3)
___________
12a ...........28b ..........4888
12a.............18b...........3558
28b - 18b = 10b..........4888 - 3558 = 1330
b = 1330 : 10 = 133
3a = 1222 - 7b = 1222 - 7*133 = 1222 - 931 = 291
a = 291 : 3 = 97
