[ 1/1Inequality]
    Assignment:Find the solution set of inequality (42+x)/(42+x) >0.9 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 42 + x ) / ( 42 + x ) >0.9         (1)
        From the definition field of divisor
         42 + x ≠ 0        (2 )

---

    From inequality(1)：
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(2)：
         x < -42 或  x ＞ -42

---

    From inequalities (1) and (2)
         x < -42 或  x ＞ -42    (3)

---

    The final solution set is :
         x < -42 或  x ＞ -42
