[ 1/1Inequality]
Assignment:Find the solution set of inequality (181101+X)/(486179+X) >0.4 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 181101 + X ) / ( 486179 + X ) >0.4 (1)
From the definition field of divisor
486179 + x ≠ 0 (2 )
From inequality(1):
The solution set is empty, that is, within the range of real numbers, the inequality will never be established!
From inequality(2):
X ∈ R (R为全体实数),即在实数范围内,不等式恒成立!
The final solution set is :
The solution set is empty,that is, the inequality will never be estatlished within the real number range.
