A is now 9 years older than B. Therefore
\n" ); document.write( "A=B+9
\n" ); document.write( "and in 10 years, A will be twice as old as B was 10 yrs ago. Therefore
\n" ); document.write( "A+10=2(B-10)
\n" ); document.write( "So;
\n" ); document.write( "B+9+10=2(B-10)
\n" ); document.write( "B+19=2B-20
\n" ); document.write( "2B-B=19+20
\n" ); document.write( "B=39
\n" ); document.write( "A=39+9=48
\n" ); document.write( "
