Assignment:Find the solution set of inequality (91+10x)/(54+4x) >2 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 91 + 10 * x ) / ( 54 + 4 * x ) >2 (1)
From the definition field of divisor
54 + 4 * x ≠ 0 (2 )
From inequality(1):
x < -13.5 或 x > 17/2
From inequality(2):
x < -27/2 或 x > -27/2
From inequalities (1) and (2)
x < -13.5 或 x > 17/2 (3)
The final solution set is :
x < -13.5 或 x > 17/2Your problem has not been solved here? Please take a look at the hot problems !
