Răspuns :
a + b = 1079
a - b = 565 + 108 = 673
a = 673 + b
673 + b + b = 1079
2b = 1079 - 673
2b = 406
b = 406 : 2
b = 203
a = 673 + 203 = 876
876 + 203 = 1079
876 - 203 = 565 + 108
673 = 673
a - b = 565 + 108 = 673
a = 673 + b
673 + b + b = 1079
2b = 1079 - 673
2b = 406
b = 406 : 2
b = 203
a = 673 + 203 = 876
876 + 203 = 1079
876 - 203 = 565 + 108
673 = 673
