\n" ); document.write( ".
\n" ); document.write( "His sister is twice his age (2A) plus 6 years. So she is 2A + 6.
\n" ); document.write( ".
\n" ); document.write( "To average their two ages, add their ages together and divide by 2. Adding their ages results

\n" ); document.write( ".
\n" ); document.write( "A + 2A + 6 = 3A + 6
\n" ); document.write( ".
\n" ); document.write( "Then dividing by 2:
\n" ); document.write( ".
\n" ); document.write( " $\"Average+Age=%283A+%2B+6%29%2F2+\"$
\n" ); document.write( ".
\n" ); document.write( "If you would like you can also divide each of the terms in the numerator by 2 and express the

\n" ); document.write( ".
\n" ); document.write( " $\"Average+Age+=+%283%2F2%29A+%2B+6%2F2+=+%283%2F2%29A+%2B+3\"$
\n" ); document.write( ".
