Răspuns :
x/2=y/4
x=2y/4
x=y/2
y-832=x
y-832=y/2 aducem la acelasi numitor
2y-1664=y
2y-y=1664
y=1664
x=1664/2= 832
x=2y/4
x=y/2
y-832=x
y-832=y/2 aducem la acelasi numitor
2y-1664=y
2y-y=1664
y=1664
x=1664/2= 832
x numarul cartilor de pe primul raft
y numarul cartilor de pe al doilea raft
x/2=y/4⇒x=y/2. 2x=y
y=x+832
2x=x+832
x=832
y=2*832=1664
y numarul cartilor de pe al doilea raft
x/2=y/4⇒x=y/2. 2x=y
y=x+832
2x=x+832
x=832
y=2*832=1664
