#x = -4.6#

Begin by distributing #-4#

#-4(2x+7) = -8x - 28#

Next lets combine our like terms

#-8x - 28 = 2x + 18 rArr-10x = 46#

Finally divide by -10 on both sides to get x by its self

#-10x = 46 rArr x = -4.6#

#x=-23/5#

Begin by simplifying the left side by distributing the #-4# to #(2x+7)#

#-4(2x+7)=2x+18#

#-8x-28=2x+18#

Subtract #2x# from both sides

#-10x-28=18#

Add 28 to both sides:

#-10x=46#

Divide #-10# from both sides

#x=-46/10#

Simplify:

#x=-23/5#
