Rozwiąż układ równań 2x + y = 1 5x - 3y = -1 wybraną metodą
Metoda przeciwnych współczynników:
{2x + y = 1 /*5
{5x - 3y = -1 /*(-2)
{10 x + 5y = 5
+ {-10 x + 6y = 2
---------------------
11y = 7 / 11
y = 7/11
{2x + y = 1 /*3
{5x - 3y = -1
{6x + 3y = 3+ {5x - 3y = -1---------------------11x = 2 |:11x = 2/11
{y = 7/11
{x = 2/11
Liczę na naj, wszystko dobrze.
