Explanation:

Method 1:
Remember multiplication or division of an inequality by a negative reverses the inequality.

Dividing both sides of #-6c >=-224# by #(-16)#
gives #c <= 14#

~~~~~~~~~~~~~~

Method 2:
Add #16c+224# to both sides
giving #224 <= 16c#
then divide both sides by #16#
to get #14 <= c#
