Read explanation.

Explanation:

#-8 - x = x - 4x#

You can subtract #4x# from #x# and get:

#-8 - x = -3x#

Then you add the #x# to both sides, which cancels out the #x# on the left side and get:

#-8 = -2x#

Then divide both sides by #-2# and get:

#4 = x#

Hope that helps.

#x=4#

Explanation:

#-8-x=x-4x#

#-8-x=-3x#

Add #3x# to both sides#

#-8-x+3x=-3x+3x#

#-8-x+3x=0#

#-8+2x=0#

Then add #-8# to both sides

#-8+2x+8=0+8#

#2x=8#

Finally, divide both sides by #2#

#(2x)/2=8/2#

#x=4#
