$x~~-0.00167504187...$ 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
