Question 1169129


if you have this:

{{{2x-3y<9}}}....solve for {{{y}}}

{{{2x-9<3y}}}

{{{3y>2x-9}}}

{{{y>2x/3-3}}}

check the coordinates:

 ({{{6}}},{{{-4}}})
{{{-4>(2*6)/3-3}}}
{{{-4>4-3}}}
{{{-4>1}}}=> false; ({{{6}}},{{{-4}}}) is not the solution to the problem


({{{-1}}},{{{-9}}})  
{{{-9>(2*-1)/3-3}}}
{{{-9>-2/3-3}}}
{{{-9>-11/3}}}=> false; ({{{-1}}},{{{-9}}})  is not the solution to the problem

({{{2}}},{{{-5}}})
{{{-5>(2*2)/3-3}}}
{{{-5>4/3-3}}}
{{{-5>4/3-9/3}}}
{{{-5>-5/3}}}=> false; ({{{2}}},{{{-5}}}) is not the solution to the problem


 ({{{-3}}},{{{-3}}})
{{{-3>(2*-3)/3-3}}}
{{{-3>(2*-1)-3}}}
{{{-3>-2-3}}}
{{{-3>-5}}}=>true; ({{{-3}}},{{{-3}}}) {{{IS}}}  the solution to the problem
