\n" ); document.write( "Jennifer is 9 years older than Kristina. Five years ago, Jennifer was twice as old as Kristina. How old are they now?
\n" ); document.write( "-----------------------------------------------------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let J = Jennifer's current age;
\n" ); document.write( " K = Kristina's current age.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Then \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "J = K + 9,\r
\n" ); document.write( "\n" ); document.write( "J - 5 = 2*(K-5).     <<<--- 5 years ago.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "As you said,  this is all you want.\r
