[ 1/2Inequality]
    Assignment:Find the solution set of inequality 9x+2 <1114 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        9 * x + 2 <1114         (1)

---

    From inequality(1)：
         x < 1112/9

---

    The final solution set is :
         x < 1112/9
[ 2/2Inequality]
    Assignment:Find the solution set of inequality 20023x^2     Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        20023 * x ^ 2 < tan x         (1)

---

    From inequality(1)：
        The solution set is empty, that is, within the range of real numbers, the inequality will never be established!

---

    The final solution set is :
        The solution set is empty,that is, the inequality will never be estatlished within the real number range.
