You can put this solution on YOUR website!
It turns out that if $\"b%3E0\"$ for something like $\"b%5Ex\"$ , then $\"b%5Ex\"$ is ALWAYS positive. It will NEVER be negative.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In this case, $\"b+=+2\"$ , so $\"2%5Ex\"$ is ALWAYS positive and NEVER negative.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore, $\"2%5Ex+=+-8\"$ is not possible and there are NO solutions \n" ); document.write( "

\n" );
