[ 1/1Inequality]
Assignment:Find the solution set of inequality (x-5)╱(x-3) ≤0.5 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( x - 5 ) / ( x - 3 ) ≤0.5 (1)
From the definition field of divisor
x - 3 ≠ 0 (2 )
From inequality(1):
3 ≤ x ≤ 7
From inequality(2):
x < 3 或 x > 3
From inequalities (1) and (2)
3 < x ≤ 7 (3)
The final solution set is :
