Ecuatie

Proposed by ixirimdiOffline
(9 comments)6.010 times displayed

 Avem o ecuatie de gradul I cu patru necunoscute: 

5x +25y + 125z + 625t = 1670
 
Se cere, de preferat, o solutie in N
(si cu o ,cât de cat, justificare a logicii folosite atunci cand ati ghicit-o)
 
REVENIRE
Propusesem odata o problema:
"Ca doi insi sa impartä o pitza in doua e simplu: unul taie si celalalt alge;
nu stiam cum se face daca sunt 4, 5,6, ... insi, sau mai multi, a.i. toti sa fie multumiti"
 
In vara asta am aflat un raspuns, da' nu cu pizza, ci cu lubenitza;
o sa vi-l spun mai pe ...diseara
(nu pretind ca  cel ma bun, da' ästa e ...)
