Answer 1

m=mere
p=pere
r= prune

p+m+r=879
m=2p+12
m=r+15


Metoda figurativa
pere   l------l
mere  l------l------l+12   }total=879
prune l------l----l -3
Pentru a forma segmentul egal la prune adaugam la suma 3
879+3=882
882-12=870 suma celor 5 parti egale
870:5=174 pere
2x174+12=348+12=360 mere
360-15=345 prune
