\r\n" );
document.write( "J - R = 5  now.   (\"jamee is 5 years older than rachell\")\r\n" );
document.write( "\r\n" );
document.write( "In 15 years, Jamee will be (J+15) years old, while Rachel will be (R+15).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, you have these two equations\r\n" );
document.write( "\r\n" );
document.write( "J - R = 5,                (1)\r\n" );
document.write( "(J+15) + (R+15) = 45.     (2)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Simplify eq(2). You will have\r\n" );
document.write( "\r\n" );
document.write( "J - R =  5,               (1')\r\n" );
document.write( "J + R = 15.               (2')\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Add equations (1') and (2')  (both sides). You will get\r\n" );
document.write( "\r\n" );
document.write( "2J = 5 + 15 = 20  ====>  j =  = 10.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus Jamee is 10 years now.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then Rachel is 10-5 = 5 years old.\r\n" );
