[ 1/1Inequality]
    Assignment:Find the solution set of inequality e^x-2*(1+x) ≤0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         e ^ x - 2 * ( 1 + x ) ≤0         (1)

---

    From inequality(1)：
         -0.768039 ≤ x ≤ 1.678347

---

    The final solution set is :
         -0.768039 ≤ x ≤ 1.678347
