Answer 2

Step-by-step explanation:

$x = - \frac{ - 4}{7} \\ y = \frac{2}{5} \\ find \\ - (x + y) = - x - y \\ = - ( \frac{ - 4}{7} + \frac{2}{5} ) \\ - ( \frac{ - 20 + 14}{35} ) \\ - (\frac{ -6 }{35} ) \\ = \frac{6}{35} \\ similarly \\ - \frac{ - 4}{7} - \frac{2}{5} \\ \frac{20 - 14}{35} \\ \frac{6}{35}$

hence both are equal
