Full solution

Q. Verify

-(-x)

by taking

x=2

Substitute $x$ with $2$ : Substitute $x$ with $2$ in the expression $-(-x)$ . $\newline$ $-(-2)$
Calculate inner negation: Calculate the inner negation first. $\newline$ $-(-2) = 2$
Check the result: Check the result. $\newline$ Since negating a negative number makes it positive, the calculation is correct.
