Resposta:

$3x + 2y = 2 \\ 2x + 3y = 3 \\ \\ x = \frac{2}{3} - \frac{2}{3} y \\ 2x + 3y = 3 \\ \\ 2 \times ( \frac{2}{3} - \frac{2}{3} y) + 3y = 3 \\ \\ \frac{4}{3} - \frac{4}{3} y + 3y = 3 \\ \\ \frac{4}{3} + \frac{5}{3} y = 3 \times (3) \\ \\ 4 + 5y = 9 \\ 5y = 9 - 4 \\ 5y = 5 \div (5) \\ y = 1$

$x = \frac{2}{3} - \frac{2}{3} \times 1 \\ \\ x = \frac{2 - 2 \times 3}{3} \\ \\ x = 0 \\ \\ (x.y) = (0.1)$
