Question

verify -(-x) = x if x= -9/11​

Answer 1

Answer:

-9/11

Step-by-step explanation:

x = -9/11

-(-x) = -(-(-9/11))

      = -9/11

Answer 2

Question :

Verify $\mathtt{-(-x) = x}$, if $\mathtt{x = \dfrac{-9}{11}}$

$\begin {gathered} \end {gathered}$

Solution :

Given,

$\mathtt{x = \dfrac{-9}{11}}$

$\begin {gathered} \end {gathered}$

$\begin {aligned} \bold {LHS = -(-x)} &\Rightarrow - \Bigg [- \Big (\dfrac{-9}{11}\Big ) \Bigg ]\\\\\\&= - \Bigg [\dfrac{9}{11} \Bigg ]\\\\\\\Rightarrow \bf -\dfrac{9}{11} &= x \Rightarrow \bold {RHS} \end {aligned}$

$\begin {gathered} \end {gathered}$

Hence, it is Verified that $\mathtt{-(-x) = x}$ . . .
