Answer
The value is $-31$.
Work Step by Step
Consider the given expression,
$\begin{align}
& 2\left( -30-\left( -3 \right) \right)-3\left( 6-9 \right)+\left( -1 \right)\left( 1-15 \right)=2\left( -27 \right)+9+14 \\
& =-54+23 \\
& =-31
\end{align}$
This implies that,
$2\left( -30-\left( -3 \right) \right)-3\left( 6-9 \right)+\left( -1 \right)\left( 1-15 \right)=-31$
Therefore, the simplified value of the expression is $-31$.
