[ 1/1Inequality]
Assignment:Find the solution set of inequality [2/(x-0.2)]+[2/(0.327-0.04)]+[2/(0.327-0.12)] ≤[x/(0.1x-0.2*0.1)] .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 2 / ( x - 0.2 ) ) + ( 2 / ( 0.327 - 0.04 ) ) + ( 2 / ( 0.327 - 0.12 ) ) ≤ ( x / ( 0.1 * x - 0.2 * 0.1 ) ) (1)
From the definition field of divisor
x - 0.2 ≠ 0 (2 )
From the definition field of divisor
0.1 * x - 0.2 * 0.1 ≠ 0 (3 )
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 < 1/5 或 x > 1/5
From inequality(3):
x < 1/5 或 x > 1/5
The final solution set is :
The solution set is empty,that is, the inequality will never be estatlished within the real number range.
