The result is 1212.

Explanation:

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

color(white)=-3(color(red)(7-11))=3(711)

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

=color(blue)-color(blue)(3*-4)=34

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

=color(blue)(3*4)

=12
