Answer 1

a-b-c = 3 876
a-(b+c)=3876
a-2997=3876
a=3876+2997
a=6873


b+c = 2997
b-c = 997
------------------
b+c+b-c=2997+997
2b=3994
b=3994:2
b=1997

c=2997-1997=1000
c=1000


a-b-c=8014
a =10 001⇒10001-b-c=8014
10001-8014=b+c
b+c=1987
b-c = 987
----------------
b+c+b-c=1987+987
2b=2974
b=2987:2
b=1487

c=1987-1487500
c=500
