a, b - numerele cerute
a+b=475
[tex] \frac{a}{b} [/tex] = [tex] \frac{2}{3} [/tex]
Rezulta b=[tex] \frac{3a}{2} [/tex]
a(amplificat cu 2) + [tex] \frac{3a}{2} [/tex] = 475
[tex] \frac{5a}{2} = 475[/tex]
[tex] \frac{5a}{2} [/tex]= 475
5a = 950
a = [tex] \frac{950}{2} [/tex]
a = 190
b = 475 - 190
b = 285
