A+b+c=8289

a+b=4001

b+c=5099

4001+c=8289 

c= 8289-4001

c=4288

b+4288=5009

b=5009-4288

b=811

a+811=4001

a= 4001- 811

a=3190

verificare: 3190+811+4288=8289

A + b + c = 8289
a + b = 4001
b + c = 5099
4001 + c = 8289
c = 8289 - 4001
c = 4288
a + 5099 = 8289
a = 8289 - 5099
a = 3190
3190 + b + 4288 = 8289
b = 8289 - 3190 - 4288
b = 811
