Question

6. Verify -(-x) = x for the following: (i) x =13/-15​

Answer 1

Step-by-step explanation:

First , take -(-x)

-(-13/-15)

During Multiplication ,

-(-) becomes +

So, we get x = 13/-15 ----(1)

Now , take x

x = 13/-15 {Given} -------(2)

So , (1) = (2)

Therefore , we get -(-x) = x

Answer 2

Answer:

$- ( - x) = x$

$x = x$

$\frac{ - ( - 13) }{ - (15)}$

$= \frac{13}{ - 15}$

$= \frac{13}{ - 15}$

Note:

-*-=+

(-1)*(-1)=+1

hence proved
