Niech:
g - girlalda
l - laski
k - komin
m - mikołaj
x = ?
4l = 32
l = 8
g + 2k = 20
g + 2*(19 - 2g) = 20
g + 38 - 4g = 20
-3g = - 18
g = 6
k = 19 - 2g
k = 19 - 2*6
k = 19 - 12
k = 7
g + k + m = 16
6 + 7 +m = 16
m = 3
g + 2m = x - 8
6 + 2 * 3 + 8 = x
x = 20
Tak by wyglądał kwadrat:
" Life is not a problem to be solved but a reality to be experienced! "
