Question

vertify it.i need solution of these 2 questions. ​

Answer 1

$\bf\huge\underline{\underline{ To \: Verify:- }}$

• $\boxed{\bf\red{ -(-x) = x }}$

• x = $\frac{2}{15}$

• $\bf \: - ( - x) = - ( - \frac{2}{15} )$

• $\bf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{2}{15}$

• $\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \ \: \: \: \: \bf \: = x$

$\rule{10cm}{0.05cm}$

• $\bf \: x = - \frac{13}{17}$

• $\bf \: - ( - x) = - ( -( - \frac{ 13}{17} ))$

• $\bf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = - \frac{13}{17}$

• $\bf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = x$

$\rule{10cm}{0.05cm}$

Answer 2

x = 2/15

-(-x) = -(-2/15) = 2/15 = x

x = -13/17

-(-x) = -(-(-13)/17) = -13/17 = x

Hence proved
