[ 1/1Inequality]
    Assignment:Find the solution set of inequality (5.8+2*t+0.8*10)*(8.4*t+91.90)/(12.6+t)/(11*10) >1.6 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 5.8 + 2 * t + 0.8 * 10 ) * ( 8.4 * t + 91.90 ) / ( 12.6 + t ) / ( 11 * 10 ) >1.6         (1)
        From the definition field of divisor
         12.6 + x ≠ 0        (2 )

---

    From inequality(1)：
         -12.6 < t < -12.052859 或  t ＞ 4.688573
    From inequality(2)：
         t < -63/5 或  t ＞ -63/5

---

    From inequalities (1) and (2)
         -12.6 < t < -12.052859 或  t ＞ 4.688573    (3)

---

    The final solution set is :
         -12.6 < t < -12.052859 或  t ＞ 4.688573
