[ 1/1Inequality]
Assignment:Find the solution set of inequality (300000+160x+9200000)/(350*x)*1.9-1.033*(x-50000)/50000 <0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 300000 + 160 * x + 9200000 ) / ( 350 * x ) * 1.9 - 1.033 * ( x - 50000 ) / 50000 <0 (1)
From the definition field of divisor
350 * x ≠ 0 (2 )
From inequality(1):
x < 0
From inequality(2):
x < 0 或 x > 0
From inequalities (1) and (2)
x < 0 (3)
The final solution set is :
