Question

Afla numarul necunoscut din egalitatile de mai jos pornind de la calculele date. (62 572+a) + 4414 = 66 716 +5 ( 62 572+a) +(4 414-a) 66716.
(8 815+ a) - 5 327 = 3 488+45.
8 815-(5327-c)= 3 488+9
(8 815-b)- 5 327=3 488+ 27.

Answer 1

(8815+a)-5327=3488+45
(8815+a)-5327=3533
8815+a=3533+5327
8815+a=8860
a=8860-8815
a=45
8815-(5327-c)=3448+9
5327-c=8815-3497
c=5327-5318
c=9
(8815-b)-5327=3488+27
8815-b=5327-3515
b=8815-8842
b=-27
