Question

a+b+c=8361 a+b=5234 b+c=5889

Answer 1

a+b+c=8361

a+b=5234 atunci inlocuim sus

5234+c=8361/-5234

c=3127

apoi inlocui in a 3

b+c=5889

b+3127=5889/-3127

b=2762

apoi la final inlocuim in a doua  a+b=5234

a+2762=5234/-2762

a=2472

Answer 2

a + b + c = 8 361
a + b = 5 234
b + c = 5 889
___________
a , b , c = ?

5 234 + c = 19 596
c = 19 596 - 5 234
c = 14 362

b + 14 362 = 5 889
b = 14 362 - 5 889
b = 8 473

a + 8 473 = 5 234
a = 8 473 - 5 234
a = 3 239
