Answer
The value is $2$.
Work Step by Step
Consider the given expression,
$\begin{align}
& 2\left( -5 \right)-\left( -3 \right)\left( 4 \right)=-10-\left( -12 \right) \\
& =-10+12 \\
& =2
\end{align}$
This implies that,
$2\left( -5 \right)-\left( -3 \right)\left( 4 \right)=2$
Therefore, the value of the expression is 2.
