[ 1/7Inequality]
    Assignment:Find the solution set of inequality (2x-1)/3-(5x+1)/2 <= 1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         ( 2 * x - 1 ) / 3 - ( 5 * x + 1 ) / 2 <= 1         (1)

    From inequality(1):
         x ≥ -1

    The final solution set is :

         x ≥ -1

[ 2/7Inequality]
    Assignment:Find the solution set of inequality 5x-2 <3(x+2) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
        5 * x - 2 <3 * ( x + 2 )         (1)

    From inequality(1):
         x < 4

    The final solution set is :

         x < 4

[ 3/7Inequality]
    Assignment:Find the solution set of inequality 3x >= 4x-1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
        3 * x >= 4 * x - 1         (1)

    From inequality(1):
         x ≤ 1

    The final solution set is :

         x ≤ 1

[ 4/7Inequality]
    Assignment:Find the solution set of inequality (5x-1)/2 >x-2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         ( 5 * x - 1 ) / 2 > x - 2         (1)

    From inequality(1):
         x > -1

    The final solution set is :

         x > -1

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

    From inequality(1):
         x ≤ 2

    The final solution set is :

         x ≤ 2

[ 6/7Inequality]
    Assignment:Find the solution set of inequality (3+5x)/2 >x-1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         ( 3 + 5 * x ) / 2 > x - 1         (1)

    From inequality(1):
         x > -5/3

    The final solution set is :

         x > -5/3

[ 7/7Inequality]
    Assignment:Find the solution set of inequality 2x+4 <= 5(x+2) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
        2 * x + 4 <= 5 * ( x + 2 )         (1)

    From inequality(1):
         x ≥ -2

    The final solution set is :

         x ≥ -2
