Question

Gasiti x si y astfel incat 12(x)+36(y)=34

Am nevoie de ajutor urgent!

Answer 1

12(x)+36(y)=34
12(x)=1·x+2, x>2  (pentru ca impartitorul>restul)
36(y)=3·y+6, y>6
=> x+2+3y+6=34
x+3y=34-8
x+3y=26
pt y=7=> x+3·7=26
x=26-21
x=5
pt y=8=>x=2, nu convine (x>2)

R: x=5, y=7
verificare: 12(5)=5+2=7
                 36(7)=3·7+6=27
                 12(5)+36(7)=7+27=34   (A)
