[ 1/1Inequality]
    Assignment:Find the solution set of inequality -5 ≤3x+4 <40 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        -5 ≤3 * x + 4         (1)
        3 * x + 4 <40         (2)

---

    From inequality(1)：
         x ≥ -3
    From inequality(2)：
         x < 12

---

    From inequalities (1) and (2)
         -3 ≤ x < 12    (3)

---

    The final solution set is :
         -3 ≤ x < 12
