document.write( "The translation to the Math language is THIS:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "W = 4D        (1)      (\"The present age of a women (W) is 4 times as her daughter's age (D)\")\r\n" );
document.write( "W = S + 29    (2)      (\"The women is 29 years older than the son (S)\")\r\n" );
document.write( "D = S +  2    (3)      (\"The difference between the daughter and the son is 2 years\")\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the difference between the women and the daughter is 27 years,\r\n" );
document.write( "\r\n" );
document.write( "so  W = 4*(W-27)  ====>  W = 4W - 108  ====>  3W = 108  ====>  W =  = 36.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  The women is 36 years old; the daughter is 36/4 = 9 years old and the son is 7 years old.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Check.   When the women was 29 years, i.e. 7 years ago, the daughter was 9-7 = 2 years old, \r\n" );

document.write( "         and these 2 years is/are the difference between the daughter and the son.\r\n" );
