Question

If X= -4/7 and y=2/5, then verfiy that: -(x+y)=(-x)+(-y)​

Answer 1

Answer:

$x=\frac{-4}{7}$     $y=\frac{2}{5}$

Substituting x and y in the equation,

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

Therefore, $(x+y)\neq(-x)+(-y)$.
