Question

Verify -x- (-y) = y - x, x = -7, y = -5

Answer 1

HELLO FRIEND

Here is your answer below,,

$- x - ( - y) = y - x \\ (x = - 7) \\ (y = - 5) \\ \\ now \: solution \: \\ \\ = > - x - ( - y) = y - x \\ = > - x + y = y - x \\ = > - ( - 7) ( - 5) = - 5 - ( - 7) \\ = > 7 - 5 = - 5 + 7 \\ = > 2 = 2$

Hence LHS is equal to RHS

I hope that helps you

Answer 2

if we take -x-(-y)=-(-7)-(-(-5))

=7-5

=2

and now we take

y-x=(-5)-(-7)

=-5+7

=2
