Answer 1

$2x + 7y = 41 \\ 10x - 7y = - 5 \\ \\ 7y = 41 - 2x \\ 10x - 7y = - 5 \\ \\ 10x - (41 - 2x) = - 5 \\ \\ x = 3 \\ \\ 10 \times 3 - 7y = - 5 \\ \\ y = 5 \\ \\ (x, y) = (3, 5) \\ \\ 2 \times 3 + 7 \times 5 = 41 \\ 10 \times 3 - 7 \times 5 = - 5 \\ \\ 41 = 41 \\ - 5 = - 5 \\ \\ La \: respuesta \: es: (x, y) = (3, 5)$
