Răspuns:
fie x-nr pisoi
y-nr labelor
z-nr urechilor
y=10+z. y=10+z. y=10+z. y=10+z
4y+2z=x 4(10+z)+2z=x 40+4z+2z=x. 40+6z=x
y=10+z. y=10+z. y=10+z. y=10+40+x/6
6z-x=40. 6z=40+x. z=40+x/6. - copiem-
y= 10/6+40+x/6. y/1=50+x/6. y=50+x x=50-y
z=40+x/6. z=40+x/6. z=40+x/6. z= 40+50-y/6
x=50-y. x=50-y. x=50-y. y=10+z. y=40
z=90-y/6. z=90+90/6. z= 30. z=30. z= 30
dar x=50-y
*x=50-40=10*
sunt 10 pisoi.
Nu știu cât e de corect, dar sper ca te-am ajutat:)
