alune= 6* nuci
alune=nuci + 100
alune+nuci?
nuci+100=6*nuci=>5*nuci=100=> numarul nucilor=100/5=20.
alune=nuci+100=> nuamrul alunelor= 120.
alune+nuci=100+20=120.
alune=nuci + 100
alune+nuci?
nuci+100=6*nuci=>5*nuci=100=> numarul nucilor=100/5=20.
alune=nuci+100=> nuamrul alunelor= 120.
alune+nuci=100+20=120.
