This is a substitution problem once you get the equations.
\n" ); document.write( "The two equations are, when j=jake and l=lisa
\n" ); document.write( "3l=j
\n" ); document.write( "j-l=400
\n" ); document.write( "you substitute the \"j\" in the second equation the the first equation.
\n" ); document.write( "so you get 3l-l=400.
\n" ); document.write( "then you solve the simple algebraic equation to get l=200.
\n" ); document.write( "then to get how many jake sells, you plug in what l equals into either equation.
\n" ); document.write( "3(200)=j
\n" ); document.write( "j=600
\n" ); document.write( "
\n" );
