Answer 2

a = 78 653;   b = 11 241;   c = 6 402

a + b - c = 78 653 + 11 241 - 6 402 = 89 894 - 6 402 = 83 492

a + b - c = 83 492

a - b - c = 78 653 - 11 241 - 6 402 = 67 412 - 6 402 = 61 010

a - b - c = 61 010

_______________________________________________________

b = 2 131;   c = 11 202

a - b - c = 63 421

a - 2 131 - 11 202 = 63 421

a = 63 421 + 11 202 + 2 131 → aplic metoda mersului invers

a = 76 754

a + b - c = 76 754 + 2 131 - 11 202 = 78 885 - 11 202 = 67 683

a + b - c = 67 683

__________________________________________________

a = 97 785;   b = 1 214;  c = 85 370

a + b - c = 97 785 + 1 214 - 85 370 = 98 999 - 85 370 = 13 629

a + b - c = 13 629

a - b - c = 97 785 - 1 214 - 85 370 = 96 571 - 85 370 = 11 201

a - b - c = 11 201
