A + B = 602
A : 2B = 2 REST 17
A = 4B + 17
4B + B + 17 = 602
5B = 602 - 17
5B = 585
B = 585 : 5
B = 117
A = 4 * 117 + 17
A = 485

A+b=602
b:2a=2, rest17 olosim teorema impartirii cu rest⇒
b=2a·2+17=4a+17 inlocuim in relatia a+b=602⇒
a+4a+17=602
5a+17=602
5a=602-17
a=585/5=117
b=4a+17=4·117+17=485
b=485
verificare 117+485=602
