$\"1+-+2+ln+x=-4\"$
\n" ); document.write( " $\"-+2+ln+x=-5\"$ Subtract 1 from both sides
\n" ); document.write( " $\"ln+x=%28-5%2F-2%29\"$ Divide both sides by -2
\n" ); document.write( " $\"e%5E%28ln+x%29=e%5E%285%2F2%29\"$ Raise both sides with base e (this undoes the natural log)
\n" ); document.write( " $\"x=12.1825\"$
\n" ); document.write( "

\n" ); document.write( "Check:
\n" ); document.write( " $\"1-2%28ln%2812.1825%29%29=-4\"$
\n" ); document.write( " $\"1-2%282.5%29=-4\"$
\n" ); document.write( " $\"1-2%282.5%29=-4\"$
\n" ); document.write( " $\"1-5=-4\"$
\n" ); document.write( " $\"-4=-4\"$ works \n" ); document.write( "

\n" );
