Let \"+m+\" = mother's age now
\n" ); document.write( "Let \"+d+\" = daughter's age now
\n" ); document.write( "----------------------------
\n" ); document.write( "\"+d+%2B+2+\" = daughter's age \"+2+\" yrs from now
\n" ); document.write( "\"+2%2A%28+d+%2B+2+%29+\" = twice daughter's age \"+2+\" yrs from now
\n" ); document.write( "----------------------------
\n" ); document.write( "\"+m+%2B+d+=+55+\"
\n" ); document.write( "\"+-d+=+m+-+55+\"
\n" ); document.write( "\"+m+-+d+=+m+%2B+m+-+55+\"
\n" ); document.write( "\"+m+-+d+=+2m+-+55+\"
\n" ); document.write( "The difference in their ages will always be \"+55+\" yrs
\n" ); document.write( "----------------------------
\n" ); document.write( "When the mother was \"+2%2A%28+d+%2B+2+%29+\", the daughter
\n" ); document.write( "was \"+2%2A%28+d+%2B+2+%29+-+%28+2m+-+55+%29+\"
\n" ); document.write( "also given:
\n" ); document.write( "\"+m+=+3%2A%28+2%2A%28+d%2B2+%29+-+%28+2m+-+55+%29+%29+\"
\n" ); document.write( "\"+m+=+3%2A%28+2d+%2B+4+-+2m+%2B+55+%29+\"
\n" ); document.write( "\"+m+=+3%2A%28+2d+-+2m+%2B+59+%29+\"
\n" ); document.write( "\"+m+=+6d+-+6m+%2B+177+\"
\n" ); document.write( "\"+7m+=+6d+%2B+177+\"
\n" ); document.write( "and, since \"+m+%2B+d+=+55+\",
\n" ); document.write( "\"+7m+=+6%2A%28+55+-+m+%29+%2B+177+\"
\n" ); document.write( "\"+7m+=+330+-+6m+%2B+177+\"
\n" ); document.write( "\"+13m+=+507+\"
\n" ); document.write( "\"+m+=+39+\"
\n" ); document.write( "and
\n" ); document.write( "\"+d+=+55+-+m+\"
\n" ); document.write( "\"+d+=+16+\"
\n" ); document.write( "The woman is 39 and the daughter is 16
\n" ); document.write( "check:
\n" ); document.write( "2 yrs from now, daughter is 18
\n" ); document.write( "twice that is 36
\n" ); document.write( "--------------
\n" ); document.write( "When the mother was 36, daughter was 13
\n" ); document.write( "Three time 13 is 39
\n" ); document.write( "OK
\n" ); document.write( "
\n" ); document.write( "
\n" );
