Let d = Diane's present age

\n" ); document.write( ":
\n" ); document.write( "Diane is 23 year older than her daughter, Amy.
\n" ); document.write( "d = a + 23
\n" ); document.write( ";
\n" ); document.write( "In 6 years Diane will be twice as old as Amy.
\n" ); document.write( "d + 6 = 2(a+6)
\n" ); document.write( "d + 6 = 2a + 12
\n" ); document.write( "d = 2a + 12 - 6
\n" ); document.write( "d = 2a + 6
\n" ); document.write( "Replace d with (a+23) from the 1st statement
\n" ); document.write( "a + 23 = 2a + 6
\n" ); document.write( "23 - 6 = 2a - a
\n" ); document.write( "17 = a; Amy is 17
