[ 1/1Inequality]
    Assignment:Find the solution set of inequality 130 = <18x+26*（6-x) = <140 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        130 <18 * x + 26 * ( 6 - x )         (1)
        18 * x + 26 * ( 6 - x ) <140         (2)

---

    From inequality(1)：
         x < 13/4
    From inequality(2)：
         x ＞ 2

---

    From inequalities (1) and (2)
         2 < x < 13/4     (3)

---

    The final solution set is :
         2 < x < 13/4
