[ 1/1Inequality]
Assignment:Find the solution set of inequality 2x-4 >(7x-11)/(x+2) .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
2 * x - 4 > ( 7 * x - 11 ) / ( x + 2 ) (1)
From the definition field of divisor
x + 2 ≠ 0 (2 )
From inequality(1):
-2 < x < 1/2 或 x > 3
From inequality(2):
x < -2 或 x > -2
From inequalities (1) and (2)
-2 < x < 1/2 或 x > 3 (3)
The final solution set is :
-2 < x < 1/2 或 x > 3Your problem has not been solved here? Please take a look at the hot problems !
