Notam:a-primul nr,b-al II-lea nr si b=a+2, c-al III-lea nr si c=b+2=a+2+2=a+4, d-al IV-lea nr si d=c+2=a+4+2=a+6.________
_________________________________
Obt ecuatia:a+b+c+d=92,inlocuim: a+(a+2)+(a+4)+(a+6)=92 ,vine: a+a+2+a+4+a+6=92,vine: 4xa+2+4+6=92,vine: 4xa+12=92,vine:4xa=92-12,vine: 4xa=80,vine: a=80:4=20,iar b=a+2=20+2=22,iar c=b+2=22+2=24,iar d =c+2=24+2=26.___________________ ________(cred ca ai vrut sa scrii nr pare,asta ori au scris gresit in enunt)
