Question

produsul a doua nr este 500. daca primul nr s-ar mari cu 5 ,atunci produsul lor ar fi 600. aflati nr-le.

Answer 1

axb=500
(a+5)xb=600
axb+5b=600
500+5b=600
5b=600-500
5b=100
b=100:5
b=20
axb=500
ax20=500
a=500:20
a=25

Answer 2

Cele doua numere: a si b
a•b=500--> b=500÷a
(a+5)•b=600-->b=600÷(a+5)
500÷a=600÷(a+5)
500•(a+5)= 600•a
500•a+ 500•5= 600•a /-500•a
2500=100•a /÷100
25=a
b=500÷a= 500÷25= 20
A=25 B=20
