Answer:

The result is #12#.

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(color(red)(-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#
