Notam merii cu "m"
perii cu "p"
prunii cu "pr"
pr=2m
p=pr+31=2m+31
2m+m+2m+31=396 /-31
5m=365 /:5
m=73
pruni=2*73=146
peri=146+31=177

fie m-nr de meri
p-nr de peri
pr-nr de pruni
m+p=396
pr=2m
p=pr+31=2m+31
m+2m+31=396
3m=396-31=365
m=[tex] \frac{365}{3} [/tex]
pr=2·[tex] \frac{365}{3} [/tex]=[tex] \frac{730}{3} [/tex]
p=[tex] \frac{730}{3} [/tex]+31=[tex] \frac{823}{3} [/tex]
numai asa merge ...nu stiu daca ai invatat fractii dar asta e
