\n" ); document.write( " $\"2AB%2BBC=AD\"$
\n" ); document.write( ".

\n" ); document.write( "You know that,
\n" ); document.write( " $\"AB%2BBC%2BCD=AD\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "Since they both equal AD set them equal to each other,
\n" ); document.write( " $\"AB%2BBC%2BCD=2AB%2BBC\"$
\n" ); document.write( "Subtract $\"AB%2BBC\"$ from both sides.
\n" ); document.write( " $\"highlight%28CD=AB%29\"$ \n" ); document.write( "
