[ 1/1Inequality]
Assignment:Find the solution set of inequality 1/(2x-1) >= 7-(3/2x) .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
1 / ( 2 * x - 1 ) >= 7 - ( 3 / 2 * x ) (1)
From the definition field of divisor
2 * x - 1 ≠ 0 (2 )
From inequality(1):
0.5 ≤ x ≤ 0.581598 或 x ≥ 4.585069
From inequality(2):
x < 1/2 或 x > 1/2
From inequalities (1) and (2)
1/2 < x ≤ 0.581598 或 x ≥ 4.585069 (3)
The final solution set is :
1/2 < x ≤ 0.581598 或 x ≥ 4.585069Your problem has not been solved here? Please take a look at the hot problems !
