​

Answer 1

Resposta:

$(x.y) = (0.0)$

Explicação passo-a-passo:

$3x + 6y = 12x = 2y \\ (3x + 6y = 2y \\ (12x = 2y \\ (3x + 4y = 0 \\ (12x - 2y = 0 \\ ( - 12x - 16y = 0 \\ (12x - 2y = 0 \\ - 18y = 0 \\ y = 0 \\ 3x + 4 \times 0 = 0 \\ x = 0 \\ (x.y) = (0.0) \\ 3 \times 0 + 6 \times 0 = 12 \times 0 = 2 \times 0 \\ 0 = 0 = 0 \\ (x.y) = (0.0)$
