Question

a+b+c=94, a+b=58, b>22 decat c, afla cele trei numere

Answer 1

a+b=58 =>c=94-58=36

b=36+22=58

a=0

Answer 2

a + b + c = 94
a + b = 58
b = c + 22


Avem urmatoarele relatii:

a + b + c = 94
a + b = 58
--------------------------- ( - ) ( Le scadem )
a + b + c - a - b = 94 - 58 ==> c = 36

Acum stim ca b = c + 22 ==> b = 36 + 22 = 58
In final ramane sa aflam doar a-ul, stiind b si c.
a + b + c = 94 ==> a + 36 + 58 = 94 ==> a + 94 = 94 ==> a = 0

Raspuns final : a = 0, b = 58, c = 36
