[ 1/1Inequality]
    Assignment:Find the solution set of inequality 3x-3+sqrt(x+3) <3x+sqrt(x+3) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
        3 * x - 3 + sqrt ( x + 3 ) <3 * x + sqrt ( x + 3 )         (1)
        From the definition field of √
         x + 3 ≥ 0        (2 )
        From the definition field of √
         x + 3 ≥ 0        (3 )

    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 ≥ -3
    From inequality(3):
         x ≥ -3

    From inequalities (1) and (2)
         x ≥ -3    (4)
    From inequalities (3) and (4)
         x ≥ -3    (5)

    The final solution set is :

         x ≥ -3
