Overview: 3 questions will be solved this time.Among them
           ☆3 inequalities

[ 1/3Inequality]
    Assignment:Find the solution set of inequality x+2 > <= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
         x + 2 >         (1)
         <= 0         (2)

---

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

---

    From inequalities (1) and (2)
         x ＞ -2    (3)

---

    The final solution set is :
         x ＞ -2
[ 2/3Inequality]
    Assignment:Find the solution set of inequality 1-2x >= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1 - 2 * x >= 0         (1)

---

    From inequality(1)：
         x ≤ 1/2

---

    The final solution set is :
         x ≤ 1/2
[ 3/3Inequality]
    Assignment:Find the solution set of inequality -(x+2) >1-2x .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        -( x + 2 ) >1 - 2 * x         (1)

---

    From inequality(1)：
         x ＞ 3

---

    The final solution set is :
         x ＞ 3
