$\huge \underline \bold \blue {♡here_is_your_answer♡:-}$

$\frac{3}{7} + ( - \frac{1}{5} ) = - \frac{1}{5} + \frac{3}{7}$

$\frac{15 - 7}{35} = \frac{ - 7 + 15}{35}$

$\frac{8}{35} = \frac{8}{35}$

Hence proved

(do second part as 1st part)

$\frac{4}{3} - \frac{2}{5} = \frac{2}{5} - \frac{4}{3}$

$\frac{20 - 6}{15} = \frac{6 - 20}{15}$

$\frac{14}{15} not \: qual \: to \: \frac{ - 14}{15}$

Hence proved

(do 2nd part same as 1st part)
