подожди решу и напишу в коиентахПошаговое объяснение:...

1. A) x - y = 5, (x+ y = 7; 5) [2x + = 15, 10x - 1 ly = 9; (4x+ 5y = 1, B) 5x+ 7y = 5; r) 3x+=y = 11, 5 3 - 2y = 8; 2. A) J(2x - 5)2 + (3y - 2)? 4x2 + 9y2 - 63, 5x - 3y = 17; Б) [(x + 3)? + (2y + 1)? = x2 + 4y? + 16, 3y - 7x = 16. ​

1. A) x - y = 5, (x+ y = 7;

5) [2x + = 15, 10x - 1 ly = 9;

(4x+ 5y = 1,

B) 5x+ 7y = 5;

r) 3x+=y = 11, 5

3

- 2y = 8;

2. A) J(2x - 5)2 + (3y - 2)? 4x2 + 9y2 - 63,

5x - 3y = 17;

Б) [(x + 3)? + (2y + 1)? = x2 + 4y? + 16,

3y - 7x = 16.
