Question

afla numarul necunoscut (c-1789)+4857= 10000 ,7000-(2813-b)=3732 si (d+3775)-3095=2680.

Answer 1

(c-1789)+4847
c-1789=10000-4857
c-1789=5143
c=5143-1789
c=3354

7000-(2813-b)=3732
2813-b=7000-3732
2813-b=3268
b=3268-2813
b=455

(d+3775)-3095=2680
d+3775=3095-2680
d+3775=415
d=3775-415
d=3360

Answer 2

c-1789=10000-4857
c-1789=5143
c=5143+1789
c=6932

2813-b=7000-3732
2813-b=3268
-b=3268-2813
-b=455
b=-455

d+3775=2680+3095
d+3775=5775
d=5775-3775
d=2000
