Calcule:
Vom nota numerele cu literele: A, B, C
Facem rezolvarea:
a + b + c = 43.526
b + c = 27.648
b - c = 148
a + 27.648 = 43.526
a = 15.878
(b + c) + (b - c) = 27.648
27.648 +148 (b + c) + (b - c) = 27.796
27.796 : 2 = 13.898
b = 13.898
13.898 + c = 27.648
c = 13.750
Facem verificarea:
15.878 + 13.898 + 13.750 = 43.526
13.898 + 13.750 = 27.648
13.898 - 13.750 = 148
