plz tell me it is urgent ​

Answer 1

Answer:

- (- x) = x

-(-13/17) = 13/17

13/17 = 13/17

HENCE, VERIFIED

Answer 2

Step-by-step explanation:

To see whether -(-x)=x; we need to put x = 2/15 in - (- x) = x

According to rules of integer, when the signs are same, we get the same sign in the answer. When the signs are different, we get different sign as answer.

$- \binom{ - 2}{15} = \frac{2}{15}$

We know that,

$( - ) \times ( - ) = ( + )$

$= > \frac{2}{15} = \frac{2}{15}$

The answer is TRUE. Now let us check for

$x = - \frac{13}{17}$

We put for

$x = - \frac{13}{7}$in

$- ( - x) = - ( - ( - \frac{13}{17})$

We know that,

$( - ) \times ( - ) = ( + ) \\ = - ( + \frac{13}{17} )$

We know that

$( - ) \times ( + ) = ( - ) \\ = - ( \frac{13}{17} ) = x$

Therefore the answer is true.
