#x=30.25# or #x=121/4#

First, we subtract #86# from both sides:

#x+86color(blue)-color(blue)86=5x-35color(blue)-color(blue)86#

Simplify:

#x=5x-121#

Subtract #5x# from both sides:

#xcolor(blue)-color(blue)5color(blue)x=5x-121color(blue)-color(blue)5color(blue)x#

Simplify:
#-4x=-121#

Divide both sides by #-4#:

#-4x-:-4=-121-:-4#

Simplify:
#x=121/4#, or #30.25# (decimal)
