    Assignment:Find the solution set of inequality （2*（t-1.5)+0.8*9)*(62.7+8.6*t)/(9+t) ≥144 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 2 * ( t - 1.5 ) + 0.8 * 9 ) * ( 62.7 + 8.6 * t ) / ( 9 + t ) ≥144         (1)
        From the definition field of divisor
         9 + x ≠ 0        (2 )

---

    From inequality(1)：
         -9 ≤ t ≤ -8.274466 或  t ≥ 7.255861
    From inequality(2)：
         t < -9 或  t ＞ -9

---

    From inequalities (1) and (2)
         -9 < t ≤ -8.274466 或  t ≥ 7.255861    (3)

---

    The final solution set is :
         -9 < t ≤ -8.274466 或  t ≥ 7.255861
