Question 668189
{{{2-c>-2}}}
Subtract 2 from both sides to isolate c
{{{-c > -4}}}
The key step: since we are multiplying or dividing by a negative number, the inequality sign flips. In this case multiply both sides by -1.
{{{c < 4}}}
Alternatively, another way to think about {{{-c>-4}}} is if you added c and 4 simultaneously to both sides to get {{{4>c}}} then as we know, putting c on the left gets us to {{{c<4}}}-- the same as the first method.
