Question

5. Verify that - (-x) is the same as x for :
13
41

​

Answer 1

Answer:

Step-by-step explanation:

To see whether -(-x) = x; we need to put  $x= 13 \ in -(-13)$

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.

$-(-13) = 13$

We know that,  

$(-)*(-) = (+)$

13 = 13

The answer is TRUE.

Now let us check for  41

We put for  

$x = 41 \ in -(-x)= x$

We know that,  

-(-x) = -(-41)

=  x= 41

= 41 = 41

Therefore, the answer is TRUE.

Thus, the answers is verified.
