Răspuns:
Explicație pas cu pas:
Fie x - primul nr. si y - al doilea nr.
x×y=2540 x=[tex]\frac{2540}{y}[/tex] x=[tex]\frac{2540}{y}[/tex]
x×(y-100)=1540 x×(y-100)=1540 [tex]\frac{2540}{y}[/tex]×(y-100)=1540
x=[tex]\frac{2540}{y}[/tex] x=[tex]\frac{2540}{y}[/tex]
[tex]\frac{2540(y-100)}{y}[/tex] = 1540 1540y=2540y-254000
x=[tex]\frac{2540}{y}[/tex] x=[tex]\frac{2540}{y}[/tex] x=10
254000=1000y y=254 y=254
