Răspuns :
iepuri albi= 2*gri
a=2g
a+g=27
3g=27
g=9 (iepuri gri)
a=18( iepuri albi)
a=2g
a+g=27
3g=27
g=9 (iepuri gri)
a=18( iepuri albi)
daca a sunt iepurii albi; b sunt iepurii gri
b=a:2=>a=2b
a+b=27
2b+b=27=> 3b=27=>b=27:3=9 nr de iepuri gri
a=2b=2×9=18 iepuri albi
cerificare: 18+9=27
b=a:2=>a=2b
a+b=27
2b+b=27=> 3b=27=>b=27:3=9 nr de iepuri gri
a=2b=2×9=18 iepuri albi
cerificare: 18+9=27
