Jeden pes zje za jeden deň jednu kosť.
Koľko psov zje za koľko dní koľko kostí?
Hmm ..., dobrá otázka. Taká zo života.
Aby ste si boli istí výsledkom, pridám ešte kontrolu riešenia:
Ak x = počet psov, y = počet dní a z = počet kostí, tak x+y+z=31
Súradnice:
N 48 06. [y-2] [x] [x+1]
E 017 07. [x-y] [y+1] [x-1]
One dog eats one bone in one day.
How many dogs eat how many bones in how many days?
Hmm ..., good question! Just like from real life.
And to make you sure of result, I added a solution check:
If x = number of dogs, y = number of days and z = number of bones, then x+y+z=31
