1286. Решите неравенства: 1) 2x + 3 < x + 1; 2) x-5> 3 - x; 3) 2 - x ≤ 3x – 10; 4) 7x - 1 > x + 5 5) 5x + 2 > 3x + 10; 6) 7x - 4 ≤ x + 14.

1. 1) \(2x + 3 < x + 1\)

   \[2x - x < 1 - 3\]

   \[x < -2\]

2. 2) \(x - 5 > 3 - x\)

   \[x + x > 3 + 5\]

   \[2x > 8\]

   \[x > 4\]

3. 3) \(2 - x \le 3x - 10\)

   \[-x - 3x \le -10 - 2\]

   \[-4x \le -12\]

   \[x \ge 3\]

4. 4) \(7x - 1 > x + 5\)

   \[7x - x > 5 + 1\]

   \[6x > 6\]

   \[x > 1\]

5. 5) \(5x + 2 > 3x + 10\)

   \[5x - 3x > 10 - 2\]

   \[2x > 8\]

   \[x > 4\]

6. 6) \(7x - 4 \le x + 14\)

   \[7x - x \le 14 + 4\]

   \[6x \le 18\]

   \[x \le 3\]

Ответ: 1) \(x < -2\); 2) \(x > 4\); 3) \(x \ge 3\); 4) \(x > 1\); 5) \(x > 4\); 6) \(x \le 3\)
