Let
\n" ); document.write( "Present age of Karen = k
\n" ); document.write( "Present age of Bill = b\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The sum of their ages is 65
\n" ); document.write( "k+b=65
\n" ); document.write( "k=65-b................(1)
\n" ); document.write( "Karen is 5 years older than twice the age of Bill
\n" ); document.write( "k=2b+5................(2)
\n" ); document.write( "Put the value of k from (1) to (2)
\n" ); document.write( "65-b=2b+5
\n" ); document.write( "-b-2b=5-65
\n" ); document.write( "-3b=-60
\n" ); document.write( "-3b/-3=-60/-3
\n" ); document.write( "b=20
\n" ); document.write( "Put the value of b in (1)
\n" ); document.write( "k=65-b
\n" ); document.write( "k=65-20
\n" ); document.write( "k=45\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Present age of Karen = k = 45 years old
\n" ); document.write( "Present age of Bill = b = 20 years old
\n" ); document.write( "
\n" ); document.write( "
\n" );
