#x=2#

#-4x -5 = -11 -2#

Let's combine #-11# and #-2#

#-4x-5=-13#

We need to isolate for #x#

add 5 to both sides

#-4x = -8#

divide by #-4# on both sides

#x=(-8)/-4# or #2#

#* * * * * * * * * * * * * * * * * * * * *#
To check our work, let's plug solve the equation, substituting #1/2# for #x#:

#-4x -5 = -11 -2#

#-4(color(red)(2)) -5 = -11 -2#

#-8-5=-11-2#

#-13 = -13#

We were right! #x=2#
