Question

Afla nr a,b,c,stiind ca suma lor este 2887,a+b=1345,iar b+c=1654

Answer 1

a+b+c = 2.887
a+b = 1.345
b+c = 1.654
c + 1.345 = 2.887, c = 2.887 - 1.345 = 1.542
a + 1.654 = 2.887, a = 2.887 - 1.654 = 1.233
b + 1.233 = 1.345 , b = 1.345 - 1.233 = 112

Answer 2

a+b+c=2887

a+b =1345

b+c=1654

c=2887-1345

c=1542

a=2887-1654

a=1233

b=2887-(1542+1233)=2887-2775

b=112

a+b+c=1542+1233+112=2887

Sper că am fost de ajutor! ✍️
