Answer 1

Respuesta:

$n = 4$

Explicación paso a paso:

$(1 - n)x + 3y - 2 = 0 \\ 3y = 2 - (1 - n)x \\ y = \frac{2}{3} - \frac{x}{3} (1 - n)$

$(n - 2)x - 2y - 1 = 0 \\ - 2y = 1 - (n - 2)x \\ y = - \frac{1}{2} + \frac{x}{2} (n - 2)$

$- \frac{1}{3} (1 - n) = \frac{1}{2} (n - 2) \\ - \frac{1}{3} + \frac{1}{3} n = \frac{1}{2} n - 1 \\ - \frac{1}{3} + 1 = ( \frac{1}{2} - \frac{1}{3} )n \\ \frac{2}{3} = \frac{1}{6} n \\ \frac{2}{3} \times 6 = n \\ 4 = n$
