2) (2;1)

Answer 2

Ответ:

$3x + 7y - 3 = 0 \\ 7x + 9y - 7 = 0$

$3x + 7y - 3 = 0 \\ 7x = 7 - 9y$

$3x + 7y - 3 = 0 \\ x = \frac{7 - 9y}{7}$

$3( \frac{7 - 9y}{7} ) + 7y - 3 = 0 \\ x = \frac{7 - 9y}{7}$

$22y = 0 \\ x = \frac{7 - 9y}{7}$

$y = 22 \div 0 = 0 \\ x = \frac{7 - 9 \times 0}{7} = \frac{7}{7} = 1$

ответ: х=1, у=0
