Answer 2

$\footnotesize \sf \purple{Solution:-}$

$\: \: \: \: \: \: \: \: \: \: \: \: \:$

$\footnotesize \sf{1) \: x +12 = 25}$

$\footnotesize \sf{\: x = 25 - 12}$

$\purple \bullet \: \boxed{\boxed{\footnotesize \sf{\: x = 13}}}$

$\: \: \: \: \: \: \: \: \: \: \: \: \:$

$\footnotesize \sf{2) \: Additive \: inverse \: of \: -6 \: is \: 6}$

$\: \: \: \: \: \: \: \: \: \: \: \: \:$

$\footnotesize \sf{3) \: \frac{ - \: 4}{19} \: \times \: \: \: \: = \frac{4}{19} }$

$\: \: \: \: \: \: \: \: \: \: \: \: \:$

$\footnotesize \sf \purple{Let \: missing \: number \: be \: x}$

$\: \: \: \: \: \: \: \: \: \: \: \: \:$

$\footnotesize \sf{x = \frac{4}{19} \times \frac{19}{ - \: 4} }$

$\footnotesize \sf{x = \cancel \frac{ 4}{19} \times \cancel \frac{19}{ - \: 4} }$

$\purple \bullet \: \boxed{\boxed{\footnotesize \sf{\: x = - 1}}}$
