Question

Verify that -(x + y) = (-x) + (-y), when : (i) x
$x = \frac{2}{3} y = \frac{5}{7}$

​

Answer 1

$- (x + y) = ( - x) + ( - y) \\ - (\frac{2}{3} + \frac{5}{7} ) = ( - \frac{2}{3}) + ( - \frac{5}{7} ) \\ - ( \frac{14 + 15}{21} ) = \frac{ - 2}{3} - \frac{5}{7} \\ \frac{ - 29}{21} = \frac{ - 14 - 15}{21} \\ \frac{ - 29}{21} = \frac{ - 29}{21}$

LHS=RHS

Hence verified.
