☆1 inequalities
[ 1/1Inequality]
Assignment:Find the solution set of inequality 3/(2x-1) ≤4/(3x+2)-1 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality：
3 / ( 2 * x - 1 ) ≤4 / ( 3 * x + 2 ) - 1 (1)
From the definition field of divisor
2 * x - 1 ≠ 0 (2 )
From the definition field of divisor
3 * x + 2 ≠ 0 (3 )
From inequality(1)：
-0.666667 ≤ x ≤ 0.5
From inequality(2)：
x < 1/2 或 x ＞ 1/2
From inequality(3)：
x < -2/3 或 x ＞ -2/3
From inequalities (1) and (2)
-0.666667 ≤ x < 1/2 (4)
From inequalities (3) and (4)
-2/3 < x < 1/2 (5)
The final solution set is :
-2/3 < x < 1/2
