You can put this solution on YOUR website!
$\"6-y+=+-y%2B2\"$
\n" ); document.write( "First, I would replace $\"y\"$ with $\"x\"$ ,
\n" ); document.write( "and write each side as an equation $\"z+=+f%28x%29\"$
\n" ); document.write( " $\"z+=+6+-+x\"$
\n" ); document.write( " $\"z+=+-x+%2B+2\"$
\n" ); document.write( "Now I can plot both lines and see where they intersect
\n" ); document.write( " $\"+graph%28+500%2C+500%2C+-10%2C+10%2C+-10%2C+10%2C+-x+%2B+6%2C+-x+%2B+2%29+\"$
\n" ); document.write( "The lines are parallel, the slopes are both $\"-1\"$ , so
\n" ); document.write( "there is no solution (place where the same $\"x\"$ is on both lines,
\n" ); document.write( "and since I made $\"x+=+y\"$ , no solution for $\"y\"$ either \n" ); document.write( "

\n" );
