Question

Exercitiul 4 va rog repede ca mai târziu trebuie sa plec

Answer 1

a + 5 819 = 7 285

a = 7 285 - 5 819

a = 1 466

Verific:     1 466 + 5 819 = 7 285

_______________________________

b - 4 283 = 3 408

b = 3 408 + 4 283

b = 7 691 → descazutul

Verific:   7 691 - 4 283 = 3 408

__________________________

8 013 - c = 3 780

c = 8 013 - 3 780

c = 4 233 → scazatorul

Verific:   8 013 - 4 233 = 3 780

____________________________

( 4 817 + 2 954 ) - a = 3 708

7 771 - a = 3 708

a = 7 771 - 3 708

a = 4 063

_________________________

b - ( 9 731 - 6 805 ) = 1 499

b - 2 926 = 1 499

b = 1 499 + 2 926

b = 4 425

_________________________

c + ( 6 815 - 4 930 ) = 5 287

c + 1 885 = 5 287

c = 5 287 - 1 885

c = 3 402

________________

( 10 000 - 8 049 ) + d = 6 281

1 951 + d = 6 281

d = 6 281 - 1 951

d = 4 330
