Se ao peso do tijolo atribuires a incógnita x ficas com uma equação a resolver:
1+1/2x=x
1=x-1/2x
1=1/2x
x=2
Assim a resposta seria que um tijolo pesa 2 kg.

Divida 1kg por 1,5
vc terá 0,666...kg
logo 1 tijolo tem 0,666...Kg porque mas metade disso será 1Kg.

1T = 1Kg + ½ T , logo
1T-1/2T = 1Kg
½ T =1Kg (2x)
2/2 T= 2Kg
Ou seja:
1T= 2Kg

Seja x o peso do tijolo:
x = 1 + x/2
2x = 2 + x
2x - x = 2
x = 2
Um Tijolo pesa 2 kg
