czesc pomoze mi ktos zrobic to zadanie bo nie wiem jak to zrobic
to sa równania.
{x+2y=2 to ma byc metoda podstawiania
{4x+2y=8
{4x-3y=-2 to ma byc metoda podstawiania
{4x+2y=3
{x-3y=3,4(w ulamku) to ma byc metoda graficzna
{2x-2y=1,75
{4x-6y=10 to ma byc metoda graficzna
{-x do 3-2y do 3-2 2 do 3=0
z gory dziekuje
