You can put this solution on YOUR website!
ln x -ln (x-4) = ln4
\n" ); document.write( "Subtracting logs --> division
\n" ); document.write( "ln(x/(x-4)) = ln(4)
\n" ); document.write( "If the logs are equal, the arguments are equal
\n" ); document.write( "x/(x-4) = 4
\n" ); document.write( "x = 4x-16
\n" ); document.write( "3x = 16
\n" ); document.write( "x = 16/3
\n" ); document.write( " \n" ); document.write( "

\n" );
