Answer:
c < -26
Step-by-step explanation:
c + 6 < -20
-6 -6
--------------------
c < -26
On the number line, the zero is in the middle.Go to the left (negative numbers) and pick -26.Make a circle without filling it,because -26 is not included. Draw a line from -26 to the left because c should be less than -26.
c CANNOT be -26 It could be -27,-28....................(less than -26)
