$\"F=3J\"$
\n" ); document.write( "Five years ago,
\n" ); document.write( " $\"F-5=4%28J-5%29\"$
\n" ); document.write( " $\"F-5=4J-20\"$
\n" ); document.write( " $\"F=4J-15\"$
\n" ); document.write( "Substituting from above,
\n" ); document.write( " $\"3J=4J-15\"$
\n" ); document.write( " $\"-J=-15\"$
\n" ); document.write( "Solve for J then use either equation to solve for F. \n" ); document.write( "
