Se um vaso pesar 4 kg,
então 1/2 vaso pesará 2 kg

ou seja 1 vaso = 2kg + 1/2 vaso(2kg) = 4kg

Assim, 1 vaso (4kg) + 1/2 vaso(2kg) = 6kg

Seja V o peso do "vaso".
Então V = 2 + V/2
V - V/2 = 2
V/2 = 2
concluindo: V = 4 kg
A partir daí 1 vaso + 1/2 vaso = V + V/2 = 3/2 X V = 3/2 X 4 = 12/2 = 6 kg
Resposta: 6 kg

simples:

2+1/2 x = 0
x = 2+2
x = 4

ou seja um vaso pesa 4kg

se x = 4

1/2 . 4 = 2

portanto 1 vaso mais 1/2 vaso pesa 6kg.

Não existe meio vaso, portanto são dois vasos o que dá 4kg.
