Question

verify that -(- x) =x for .

x=11/15​

Answer 1

Answer:

-(-x)=x

Step-by-step explanation:

We know,

Additive inverse of x= - x = - 11/15

& Additive inverse of - x= -(-x) => -11/15 = 11/15

Now,

-11/15 + 11/15 = 0

Hence,

-(-x)=x

Answer 2

Answer:

Step-by-step explanation:

NOTE THAT : – × – = +

– × + = –

+ × – = –

+ × + = +

-(- x) =x for x=11/15

=> -[-(11/15)] = (-1) × (-11/15)

= (-1×-11)/15

= 11/15
