Question 791200
If {{{4x-1<0}}} then {{{abs(4x-1)=1-4x>=11}}}
{{{-4x>=11-1}}}
{{{-4x>=10}}}
{{{x<=-5/2}}}, reversal of order symbol because division by a NEGATIVE number.


If {{{4x-1>=0}}} then {{{abs(4x-1)=4x-1>=11}}}
{{{4x>=11+1}}}
{{{4x>=12}}}
{{{x>=3}}}


SOLUTION:  {{{highlight(x<=-5/2)}}}  OR  {{{highlight(x>=3)}}}
