Assignment:Find the solution set of inequality (696+x)/(724+x) >0.97 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 696 + x ) / ( 724 + x ) >0.97 (1)
From the definition field of divisor
724 + x ≠ 0 (2 )
From inequality(1):
x > 628/3
From inequality(2):
x < -724 或 x > -724
From inequalities (1) and (2)
x > 628/3 (3)
The final solution set is :
x > 628/3Your problem has not been solved here? Please take a look at the hot problems !
