Question 1043075
{{{system(y=x-3,xy=A,(x-3)(y-3)=A-176)}}}


{{{system(x(x-3)=A,xy-3x-3y+9=A-176)}}}


Notice again that {{{xy=A}}}.
-
{{{-xy+3x+3y-9=176-A}}}
{{{3x+3y-9=176}}}
{{{3x+3y=185}}}
{{{3x+3(x-3)=185}}}
{{{6x-9=185}}}
{{{6x=194}}}
{{{3x=97}}}
{{{highlight(x=97/3)}}}
and
{{{highlight(y=97/3-3)}}}

You still want to simplify those results.
