, with as this would make the denominator 0, and therefore, an UNDEFINED inequality
----- Multiplying both sides by LCD, x - 3

-------- Subtracting 3 from both sides

--------- Subtracting x from both sides

-------- Inequality sign changes when dividing by a negative value

Now, we have the CRITICAL VALUES:
This means that we will have THREE (3) TEST-INTERVALS to determine whether or not values
in the intervals SATISFY the ORIGINAL inequality: . These TEST INTERVALS are:
1) 
2) , and
3)
Testing with test value: , becomes: 


As the above is TRUE, the test-interval: IS a solution
Testing with test value: , becomes: 


As the above is FALSE, the test-interval: IS NOT a solution
Testing with test value: , becomes: 


As the above is TRUE, the test-interval: IS a solution
In interval notation, this is: (- oo, ½) ᑌ (3, oo) , or (  ) ᑌ (  )
