\"21x+%2B+14+=+7%283x+%2B+a%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"21x%2B14=21x%2B7a\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"21x-21x%2B14=7a\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"14=7a\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"a=2\"-----------this will make the equation always true.
