Simple with those. Add the members eliminates y. Subtract the members eliminates x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "That means do this:
\n" ); document.write( "\"%28x%2By%29%2B%28x-y%29=-3%2B13\"
\n" ); document.write( "and then
\n" ); document.write( "\"%28x%2By%29-%28x-y%29=-3-13\"
\n" ); document.write( "
\n" );
