Question

va roggg mult ,am nevoie urgent​

Answer 1

Răspuns:

x=suma depusa la banca care acorda 5%

y-suma depusa la banca care acorda 6%

x+y=2300⇒x=2300-y (relatia 1)

x+5%x+y+6%y=2427⇔105x+106y=242700 (relatia 2)

inlocuind x din relatia 1 in reltia 2⇒105(2300-y)+106y=242700⇔241500-105y+106y=242700=> y=1200    x=1227

Succes la scoala :) !
