#-10x-6#

#4+x+(-10)-11x#
#=># Remove parentheses

Rule: #(-a)=-a#

#=4+x-10-11x#

Why + changes to -?
#+# changes to #-# because of #-# infront on #10#, because of #-10#

Rule:
+ and - #=># -
+ and + #=># +
- and - #=># +

Now group like terms #=># -11x+x+4-10

Add similar elements #=># #-11x+x=-10x#
#= 10x+4-10#

Finally subtract numbers #4-10=-6#
#=-10x-6#
