Let $\"y+=+5%5Ex\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"%2825%5Ex%29-8%2A%285%5Ex%29=-16+\"$
\n" ); document.write( " $\"%285%5E%282x%29%29-8%2A%285%5Ex%29=-16+\"$
\n" ); document.write( " $\"%285%5Ex%29%5E2-8%2A%285%5Ex%29=-16+\"$
\n" ); document.write( " $\"y%5E2-8y=-16\"$
\n" ); document.write( " $\"y%5E2-8y%2B16=0\"$
\n" ); document.write( " $\"%28y-4%29%28y-4%29=0\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y=4\"$
\n" ); document.write( " $\"5%5Ex=4\"$
\n" ); document.write( " $\"x=log%28+5%2C+4%29\"$ \n" ); document.write( "
