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

Peso do tijolo = x

Logo:

X = 1 + X/2

2X= 2 + X

X = 2

2x = 2 + x
2x - x = 2
