Question

Suma a trei numer este 9 289. Suma doua este 5001, iar suma ultimelor doua este 6 099. Afla cele trei numere.

Answer 1

a+b+c=9289

a+b=5001

b+c=6099

a=5001-b

c=6099-b

5001-b+b+6099-b=9289

5001-2b+6099-b=9289

5001-2b-b=9289-6099

5001-b=3190

b=5001-3190

b=1811

a=5001-1811

a=3190

c=6099-1811

c=4288

Rezultate: a=3190; b=1811; c=4288

Answer 2

a+b+c=9289; a+b=5001=> b= 5001-a; b+c= 6099 => c= 6099-b=> c= 6099-5001+a=> c= 1098+a; a+5001-a+1098+a= 9289; 6099+a= 9289-> a= 3190; b=5001-3190-> b= 1811; c=6099-1811-> c= 4288
