Let
\n" ); document.write( "Present age of Janey = j
\n" ); document.write( "Present age of Peter = p\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Janey is twice as old as Peter.
\n" ); document.write( "j=2p.........(1)
\n" ); document.write( "The sum of their ages is 5 times Peter's age less 48.
\n" ); document.write( "j+p=5p-48
\n" ); document.write( "j=5p-48-p
\n" ); document.write( "j=4p-48.........(2)
\n" ); document.write( "Put the value of j from (1) to (2)
\n" ); document.write( "2p=4p-48
\n" ); document.write( "2p-4p=-48
\n" ); document.write( "-2p=-48
\n" ); document.write( "-2p/-2=-48/-2
\n" ); document.write( "p=24
\n" ); document.write( "Put the value of p in (1)
\n" ); document.write( "j=2p
\n" ); document.write( "j=2*24
\n" ); document.write( "j=48\r
\n" ); document.write( "\n" ); document.write( "Present age of Janey = j = 48 years old
\n" ); document.write( "Present age of Peter = p = 24 years old
\n" ); document.write( "
\n" ); document.write( "
\n" );
