           ☆3 inequalities

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

---

    From inequality(1)：
         1 < T < 3/2
    From inequality(2)：
         T < 1 或  T ＞ 1

---

    From inequalities (1) and (2)
         1 < T < 3/2     (3)

---

    The final solution set is :
         1 < T < 3/2
[ 2/3Inequality]
    Assignment:Find the solution set of inequality (1-t)16+(1+2*t)4-(1+t) <= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 1 - t ) * 16 + ( 1 + 2 * t ) * 4 - ( 1 + t ) <= 0         (1)

---

    From inequality(1)：
         t ≥ 19/9

---

    The final solution set is :
         t ≥ 19/9
[ 3/3Inequality]
    Assignment:Find the solution set of inequality (1-t)4+(1+2*t)2-(1+t) >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 1 - t ) * 4 + ( 1 + 2 * t ) * 2 - ( 1 + t ) >0         (1)

---

    From inequality(1)：
         t < 5

---

    The final solution set is :
         t < 5
