Best ResponseYou've already chosen the best response.0if you don't like the decimal action in the second equation multiply both sides by 100 giving you 5N+10D=310

Best ResponseYou've already chosen the best response.0you could also divide both sides of that equation by 5 giving you N+2D=310/5

Best ResponseYou've already chosen the best response.0you have the system is: N+D=37 N+2D=62 surely this looks less ugly to solve
