[ 1/1Inequality]
    Assignment:Find the solution set of inequality (2k-3)/(4-k) >= -1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 2 * k - 3 ) / ( 4 - k ) >= -1         (1)
        From the definition field of divisor
         4 - x ≠ 0        (2 )

---

    From inequality(1)：
         -1 ≤ k ≤ 4
    From inequality(2)：
         k < 4 或  k ＞ 4

---

    From inequalities (1) and (2)
         -1 ≤ k < 4    (3)

---

    The final solution set is :
         -1 ≤ k < 4
