Algebra.Com's Answer #54955 by stargrl12566(16)![]() ![]() ![]() You can put this solution on YOUR website! 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( " |
