Overview: 2 questions will be solved this time.Among them
           ☆2 inequalities

[ 1/2Inequality]
    Assignment:Find the solution set of inequality 2-x/x-1 <= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        2 - x / x - 1 <= 0         (1)
        From the definition field of divisor
        x ≠ 0        (2 )

---

    From inequality(1)：
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(2)：
         x < 0 或  x ＞ 0

---

    From inequalities (1) and (2)
         x < 0 或  x ＞ 0    (3)

---

    The final solution set is :
         x < 0 或  x ＞ 0
[ 2/2Inequality]
    Assignment:Find the solution set of inequality x/x-1 >= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x / x - 1 >= 0         (1)
        From the definition field of divisor
        x ≠ 0        (2 )

---

    From inequality(1)：
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(2)：
         x < 0 或  x ＞ 0

---

    From inequalities (1) and (2)
         x < 0 或  x ＞ 0    (3)

---

    The final solution set is :
         x < 0 或  x ＞ 0
