Answer 2

Step-by-step explanation:

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: question$

$what \: no. \: should \: be \: subtracted \: from \frac{ - 13}{5} \: to \: get \: - 2$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: solution$

$let \: the \: number \: to \: get \: - 2\: be \: x \:$

$according \: to \: question \:$

$\: \: \: \: \: \: \frac{ - 13}{5} - x = - 2$

$\: \: \: \: \frac{ - 13}{5} + 2 = x$

$\: \: \: \frac{ - 13 + 10}{5}$

$\: \: \: \: \: \: \: \: x = \frac{ - 3}{5}$

$hence \: the \: other \: no. \: is \: \frac{ - 3}{5}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: check$

$\frac{ - 13}{5} - ( \frac{ - 3}{5}) = - 2$

$\frac{ - 13}{5} + \frac{3}{5} = - 2$

$\frac{ - 13 + 3}{5} = - 2$

$\frac{ - 10}{5} = - 2$

$- 2 = - 2$

$hence \: verified$
