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

[ 1/2Inequality]
    Assignment:Find the solution set of inequality x >5 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x >5         (1)

---

    From inequality(1)：
         x ＞ 5

---

    The final solution set is :
         x ＞ 5
[ 2/2Inequality]
    Assignment:Find the solution set of inequality 3x^2     Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        3 * x ^ 2 < e         (1)

---

    From inequality(1)：
        x ∈ Φ (Φ is empty)that is, the inequality will never be estatlished within the real number range!

---

    The final solution set is :
        x ∈ Φ (Φ is empty)that is, the inequality will never be estatlished within the real number range!
