You can put this solution on YOUR website!

\n" ); document.write( "\n" ); document.write( "\"7r=5r\"...there is no solution; you do NOT have such a number \"r\" that makes \"7r=5r\" true \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"7r=5r\"...here, you cancel \"r\" by dividing both sides by \"r\"\r
\n" ); document.write( "\n" ); document.write( "\"7cross%28r%29=5cross%28r%29\"...and you got \"7=5\" which is NOT true
\n" ); document.write( "
