         x >0         (1)

---

    From inequality(1)：
         x ＞ 0

---

    The final solution set is :
         x ＞ 0
[ 2/5Inequality]
    Assignment:Find the solution set of inequality 10-10x >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        10 - 10 * x >0         (1)

---

    From inequality(1)：
         x < 1

---

    The final solution set is :
         x < 1
[ 3/5Inequality]
    Assignment:Find the solution set of inequality 10-10x-10x^(2) >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        10 - 10 * x - 10 * x ^ ( 2 ) >0         (1)

---

    From inequality(1)：
         -1.618034 < x < 0.618034

---

    The final solution set is :
         -1.618034 < x < 0.618034
