Question 74217
{{{1/(3x)<12}}}
{{{cross(3x)(1/cross(3x))<(12)(3x)}}}Multiply both sides by 3x
{{{1<36x}}}Divide both sides by 36
{{{1/36<x}}}
So {{{x>1/36}}} 
note: remember the solution is not {{{x=1/36}}} because you can plug in x=2 and get
{{{1/3(2)<12}}}
{{{1/6<12}}}And it will still be true. So the true answer is x is greater than 1/36 or {{{x>1/36}}}
