Answer 1

Ответ:

$y = x + 6 \\ \frac{1}{3} x + y = 2 \\ \\ \frac{1}{3} x + x + 6 = 2 \\ x = - 3 \\ y = - 3+6\\ у=3</p><p>[tex]y + x = 0 \\ 4x + y = 6 \\ \\ y = - x \\ 4x - x = 6 \\ 3x = 6 \\ x = 2 \\ y = - 2$

$x = - 1 \\ 2x + y = 3 \\ \\ 2 \times ( - 1) + y = 3 \\ y = 3 + 2 \\ y = 5 \\ 2x + 5 = 3 \\ 2x = 3 - 5 \\ 2x = - 2 \\ x = - 1$
