\n" ); document.write( " $\"L%2BW=54\"$
\n" ); document.write( " $\"L%2B%28L-12%29=54\"$
\n" ); document.write( " $\"2L-12=54\"$
\n" ); document.write( " $\"2L=66\"$
\n" ); document.write( " $\"highlight%28L=33%29\"$
\n" ); document.write( " $\"W=L-12=33-12\"$
\n" ); document.write( " $\"highlight%28W=21%29\"$ \n" ); document.write( "
