The result is $12$ $12$ .

First, do the subtraction that's inside the parentheses (in red). After that, do the multiplication of the two numbers (in blue).

$= - 3 (7 - 11)$ $color(white)=-3(color(red)(7-11))$

$= - 3 (- 4)$ $=-3(color(red)(-4))$

$= - 3 \cdot - 4$ $=color(blue)-color(blue)(3*-4)$

$=color(red)cancelcolor(blue)-color(blue)(3*)color(red)cancelcolor(blue)-color(blue)4$

$=color(blue)(3*4)$

$=12$
