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

---

    From inequality(1)：
         x ≥ 3/4

---

    The final solution set is :
         x ≥ 3/4
[ 2/2Inequality]
    Assignment:Find the solution set of inequality x^2 ≤1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x ^ 2 ≤1         (1)

---

    From inequality(1)：
         -1 ≤ x ≤ 1

---

    The final solution set is :
         -1 ≤ x ≤ 1
