\n" ); document.write( "Peter is 36 years old. Peter is twice as old as Jun was when Peter was as old as Jun is now. How old is Jun?
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~\r

\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "Let J be the Jun's age now.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "How many years ago Peter was as old as Jun is now ? --- ANSWER :  36-J years ago.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "How old was Jun then ? --- ANSWER :  J - (36-J)  = 2J-36  years old.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now we can write the setup equation, as we read the problem\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    36 = 2*(2J-36).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Simplify and find J from this equation\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    36 = 4J - 72\r\n" );
document.write( "\r\n" );
document.write( "    36 + 72 = 4J\r\n" );
document.write( "\r\n" );
document.write( "      108   = 4J\r\n" );
document.write( "\r\n" );
document.write( "       J    = 108/4 = 27.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  Jun is 27 years old.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.   Peter was as old as Jun is now 36-27 = 9 years ago.\r\n" );
document.write( "\r\n" );
document.write( "         9 years ago Jun was 27-9 = 18 years.\r\n" );
document.write( "\r\n" );
document.write( "         Peter's age now (36) is twice Jun's age then  (9 years ago Jun was 18 years old.\r\n" );
