Question 882940
Solve:  1/(x-7) <= 0 
-----
Draw a number line.
Plot x = 7 on the line (because it cannot be a solution)
---
Test value to the left and to the right of x = 7 to find the solution set::
If x < 7 you get 1/- <= 0 which is true
---
If x > 7 you get 1/+ <= 0 which is false
=====
Solution: x < 7
