You can put this solution on YOUR website!
$\"e%5E%28-x%29=0.5\"$
\n" ); document.write( "Take the natural log of both sides:
\n" ); document.write( " $\"ln%28e%5E%28-x%29%29=ln%280.5%29\"$
\n" ); document.write( "Using exponent log property:
\n" ); document.write( " $\"-xln%28e%29=ln%280.5%29\"$
\n" ); document.write( "Since ln(e)=1, you can simplify:
\n" ); document.write( " $\"-x=ln%280.5%29\"$
\n" ); document.write( " $\"highlight%28x=-ln%280.5%29%29\"$
