Log4X-Log4(X-4)=1
\n" ); document.write( "the first two 4's are the bases.
\n" ); document.write( "------------
\n" ); document.write( " $\"log%284%2Cx%29+-+log%284%2C%28x-4%29%29+=+1\"$
\n" ); document.write( " $\"log%284%2Cx%2F%28x-4%29%29+=+1\"$
\n" ); document.write( "x/(x-4) = 4
\n" ); document.write( "x = 4(x-4)
\n" ); document.write( "x = 4x-16
\n" ); document.write( "3x = 16
\n" ); document.write( "x = 16/3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
