           ☆2 inequalities

[ 1/2Inequality]
    Assignment:Find the solution set of inequality 3*(7m+4)/7+(-m-4) <= 0, .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        3 * ( 7 * m + 4 ) / 7 + ( -m - 4 ) <= 0 ,         (1)

---

    From inequality(1)：
         m ≤ 8/7

---

    The final solution set is :
         m ≤ 8/7
[ 2/2Inequality]
    Assignment:Find the solution set of inequality (7m+4)/7+5*(-m-4) >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 7 * m + 4 ) / 7 + 5 * ( -m - 4 ) >0         (1)

---

    From inequality(1)：
         m < -34/7

---

    The final solution set is :
         m < -34/7
