[ 1/1Inequality]
    Assignment:Find the solution set of inequality (0.8+2t+0.8*8.6)*(7.9t+91.07)/(11+t)/86 >= 1.6 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 0.8 + 2 * t + 0.8 * 8.6 ) * ( 7.9 * t + 91.07 ) / ( 11 + t ) / 86 >= 1.6         (1)
        From the definition field of divisor
         11 + x ≠ 0        (2 )

---

    From inequality(1)：
         -11.242525 ≤ t ≤ -11 或  t ≥ 4.583537
    From inequality(2)：
         t < -11 或  t ＞ -11

---

    From inequalities (1) and (2)
         -11.242525 ≤ t < -11 或  t ≥ 4.583537    (3)

---

    The final solution set is :
         -11.242525 ≤ t < -11 或  t ≥ 4.583537
