Question

2. Dacă x+1 supra 5x+1= 0,(27), valoarea lui x este: ​

Answer 1

(x+1)/(5x+1)=0,(27)

Putem scrie 0,(27) sub forma de fractie, transformand-o astfel:

0,(27)=27/99=3/11

Prin urmare, ecuatia va arata asa:

(x+1)/(5x+1) = 3/11

11(x+1)=3(5x+1)

11x+11=15x+3

11x-15x= 3-11

-4x= -8 /×(-1)

4x=8

x=2
