#6x-12#

Explanation:

To combine like terms you need to bring all of the x's together and all of the numbers together.

To start we can expand the brackets.

#2(4x-4)-2(x+2)#
#=8x-8-2x-4#

Now we can add all of the terms with x's in them together and all the the terms that are just numbers together.

#=8x-2x-8-4#
#=6x-12#

Now all the like terms are combined.
