document.write( "Its solutions are the sets of the temperature T values that are remoted from 91.2 at least by 3.5.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "These values fall in two sets:  a)  T <= 91.2-3.5 = 87.7,   and  b)  T >= 91.2+3.5 = 94.7.\r\n" );

document.write( "\r\n" );
document.write( "Answer.  The solution is the union of these two sets  {T <= 87.7} U {T >= 94.7}.\r\n" );
