Question 207838
One of the most important rules of first level algebra is "WHEN YOU MULTIPLY OR DIVIDE BOTH SIDES OF AN INEQUALITY BY A NEGATIVE NUMBER, YOU MUST REVERSE THE DIRECTION OF THE INEQUALITY SIGN!"  


You have to do this here, when you multiply both sides by -1/2:
{{{-2x > 1/9 }}}

{{{(-1/2)*(-2x) > (-1/2)*(1/9) }}}
{{{x < -1/18 }}}
