Question

variety that -(x+y)=(-x)+(-y)when x=2/3 ,y=5/7​

Answer 1

Answer:

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

HENCE PROVE THAT -(x+y)= (-x) + (-y)
