Right now, Ann is $\"A+\"$ years old, Jane is $\"J\"$ years old.
\n" ); document.write( "Five years ago, Ann was $\"A-5\"$ and Jane was $\"J-5\"$ .
\n" ); document.write( " $\"J-5=4%28A-5%29\"$
\n" ); document.write( " $\"J-5=4A-20\"$
\n" ); document.write( "1. $\"J=4A-15\"$
\n" ); document.write( "In 13 years, Ann will be $\"A%2B13\"$ and Jane will be $\"J%2B13\"$ .
\n" ); document.write( " $\"J%2B13=%28A%2B13%29%2B6\"$
\n" ); document.write( " $\"J%2B13=A%2B19\"$
\n" ); document.write( "2. $\"J=A%2B6\"$
\n" ); document.write( "Substitute from eq. 1,
\n" ); document.write( " $\"4A-15=A%2B6\"$
\n" ); document.write( " $\"3A=21\"$
\n" ); document.write( " $\"highlight%28A=7%29\"$
\n" ); document.write( "Then use either equation to solve for $\"J\"$
\n" ); document.write( " $\"J=A%2B6\"$
\n" ); document.write( " $\"J=7%2B6\"$
\n" ); document.write( " $\"highlight%28J=13%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
