Question

verify that ( -x ) = for
x = 13/17​

Answer 1

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 some, we get the same signs in the answer. When the signs are different we get different signs answer

-(-12/15)=2/15

we know that (-)×(-)=(+)

2/15=2/15

The answer is true

Now let us check for

x=-13/17

we put for x=-13/17 in -(-x) =x

_(-x) =(+13/17)

We know that, (-)×(+)=(-)

=-(13/17)=x

Therefore, the answer is true.
