Olá!

2.(x+3) = 12

2x + 6 = 12

x = (12 - 6) / 2

x = 6 / 2

x = 3

Prova real:

2.(3+3) = 12

2.(6) = 12

12 = 12

Espero ter ajudado, tenha um bom dia.

Oi, bom dia!

Resposta:

S = {3}.

Explicação passo-a-passo:

2 (x + 3) = 12 —> Equação do 1º grau.

2x + 6 = 12

2x = 12 – 6

2x = 6

x = \frac{6}{2}

x = 3. —> S = {3}.

Espero ter te ajudado e bons estudos para você! ;)
