Required

Examine Neetu's statement

Neetu's statement is sometimes true.

First,

Let d = 5

`-8 + d` becomes

`-8 + 5`

`-3`

In this case, Neetu's statement is incorrect

However,

Let d = 10

`-8 + d` becomes

`-8 + 10`

`2`

In this case, Neetu's statement is correct.

So, we can conclude that;

Neetu's statement is sometimes true
