Then multiply $3$ by the answer to the bracket.

$3 \left[- 2 + \textcolor{red}{\left(- 3\right) \left(15\right)} \div 5\right]$

$= 3 \left[- 2 + \textcolor{red}{\left(- 45\right)} \div 5\right]$

$= 3 \left[- 2 + \textcolor{b l u e}{\left(- 45\right) \div 5}\right]$

$= 3 \left[- 2 + \textcolor{b l u e}{\left(- 9\right)}\right]$

$= 3 \left[- 11\right]$

$= - 33$
