Answer 2

Given,

$\[\left( { - 10} \right) + \_\_ = \left( { - 16} \right)\]$

Solution,

Know that, $\[\left( { - a} \right) + \left( { - a} \right) = - \left( {2a} \right)\]$

$\[\begin{array}{l}\left( { - 10} \right) + \_\_ = \left( { - 16} \right)\\ \Rightarrow \left( { - 10} \right) + \_\_ = \left( { - 10} \right) + \left( { - 6} \right)\end{array}\]$

Compare the both side terms,

$\[ \Rightarrow \_\_ = \left( { - 6} \right)\]$

Hence the answer will be $\[\left( { - 6} \right)\].$
