\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "Let x be the Grace age;  Then Faith is (x+10) years old.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Eight years ago they were  (x-8) (Grace)  and  ((x+10)-8) = (x+2)  (Faight) years old.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The condition says\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    x+2 = 3*(x-8).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From this equation\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    x+2 = 3x - 24\r\n" );
document.write( "\r\n" );
document.write( "    2 + 24 = 3x - x\r\n" );
document.write( "\r\n" );
document.write( "    26     = 2x\r\n" );
document.write( "\r\n" );
document.write( "     x     = 26/2 = 13.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  Grace is 13 years old;  Faith is 13+10 = 23 years old.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.  8 years age they were  13-8 = 5  and  23-8 = 15 years old with the ratio \"15%2F5\" = 3.  ! Correct !\r\n" );
