           ☆4 inequalities

[ 1/4Inequality]
    Assignment:Find the solution set of inequality 2X1+X <= 1200 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        2 * X * 1 + X <= 1200         (1)

---

    From inequality(1)：
         X ≤ 400

---

    The final solution set is :
         X ≤ 400
[ 2/4Inequality]
    Assignment:Find the solution set of inequality 3X1+4X2 <= 2400 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        3 * X * 1 + 4 * X * 2 <= 2400         (1)

---

    From inequality(1)：
         X ≤ 2400/11

---

    The final solution set is :
         X ≤ 2400/11
[ 3/4Inequality]
    Assignment:Find the solution set of inequality x1+x2 <= 800 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x * 1 + x * 2 <= 800         (1)

---

    From inequality(1)：
         x ≤ 800/3

---

    The final solution set is :
         x ≤ 800/3
[ 4/4Inequality]
    Assignment:Find the solution set of inequality X1-x2 <= 450 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         X * 1 - X * 2 <= 450         (1)

---

    From inequality(1)：
         X ≥ -450

---

    The final solution set is :
         X ≥ -450
