#x~~-0.00167504187...# Approximate answer

#x=-1/597" " # Precise answer

The symbol % is a bit like a unit of measurement but one that is worth #1/100# of something that follows it.

So #x%" "->" "x xx%" "->" "x xx 1/100 = x/100#
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Thus we have: #x/100" "=2x +1/300#

(get the #x# terms together and on their own)

#x/100 -2x=1/300#

(get rid of the #1/100# by multiplying #ul(color(white)(.)"all of both sides"color(white)(.)) # by 100 )

#x-200x=1/3#

#-199x=1/3#

Multiply both sides by (-1) to make #-199x# positive

#199x=-1/3#

#x=-0.00167504187...# This decimal is not a precise answer

#x=-1/597 # Precise answer
