Question 230822
Hello, 
Here's what you want to do with equations. Get the letter (in this case c all alone on one side of the equal sign. To do that, you subtract 4 on both sides of the equation. 

            C + 4 - 4 = -14 - 4

You see what happens? +4 minus 4 is 0 so now you have C all by itself. 

So here's what the answer is: 

                  C = - 18

If you are confused how I got -18. Think of it like this. If the temperature is 
14 below zero and it got 4 degrees colder, what would be the temperature? 
That's right   -18

Now plug the -18 into the original equation:

                       -18 + 4 = -14
Then doing the rest of the calculation you see 
  
                        -14 = -14
