document.write( "In English,  \"four times older\" means \"five times as old as\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, if \"x\" is the son's current age, then the father's current age is 5x, according to the condition and correct interpretation.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "In 14 years . . . \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "5x + 14 = 2*(x+14)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "5x + 14 = 2x + 28\r\n" );
document.write( "\r\n" );
document.write( "5x - 2x = 28 - 14 \r\n" );
document.write( "\r\n" );
document.write( "3x = 14  ====>  x = 14/3  is not an integer number.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the problem formulation is DEFECTIVE, since the ages in the age problems are ALWAYS (TRADITIONALLY !) integer numbers.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It means that you incorrectly use and interpret this figure of speech \"four times older\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "I understand it VERY WELL, since myself made this mistake, until I learned the truth from other tutors at this forum.\r\n" );
document.write( "\r\n" );
document.write( "So, I wish you to IMPROVE YOUR ENGLISH in this part AS SOON AS YOU CAN.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It is especially important, since you try to create your own problem/problems directly translating from your native language.\r\n" );
