Question

Verify: $-(-\mathrm{x})=\mathrm{x}$ for $\mathrm{x}=\frac{3}{5}$.

Answer 1

We have to verify $-(-\mathrm{x})=\mathrm{x}$

Here,

$\begin{array}{rcl}\mathrm{L}.\mathrm{H}.\mathrm{S}.& =& -(-\mathrm{x})\\ & =& -\left(\frac{-3}{5}\right)\\ & =& \frac{3}{5}\\ & =& \mathrm{x}\\ & =& \mathrm{R}.\mathrm{H}.\mathrm{S}.\end{array}$

Hence Verified
