Question

Verify that -(-x) = x, when : (i) x 8/5
​

Answer 1

Answer:

LHS = -(-x)

According to question, x = 8/5

= -(-8/5)

There is one minus sign outside the bracket, so it will change the sign of content inside the bracket.

= 8/5

Now,

RHS = x

It is given in the question that value of x is 8/5

So, RHS = 8/5

Therefore, LHS = RHS

It means that -(-x) = x.

Hence proved.
