\r\n" );
document.write( "Let Skyler age be x.\r\n" );
document.write( "\r\n" );
document.write( "Then the Destiny age is (x-6) years.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Next, write equations for their ages in 4 years, as you read the problem\r\n" );
document.write( "\r\n" );
document.write( "    (x+4) + ((x-6)+4) = 44.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Simplify and find x\r\n" );
document.write( "\r\n" );
document.write( "    x + 4 + x - 6 + 4 = 44\r\n" );

document.write( "CHECK.  (a) Destiny is 21-6 = 15 years old.\r\n" );
document.write( "\r\n" );
document.write( "        (b)  In 4 years the sum of their ages will be  (21+4) + (15+4) = 25 + 19 = 44.    ! Correct !\r\n" );
