Answer:
c = 22
Step-by-step explanation:
9 - c = -13
To solve this, we must get c alone on one side.
So, subtract 9 from both sides.
9 - c = -13
-c = -22
Subtracting 9 from both sides gives us -c = -22. However, we want a positive c, not negative c.
So normally, divide both sides by negative 1.
[In this case, since both sides have a negative sign, the cancel each other out, so you can just get rid of both negative signs.]
-c = -22
c = 22
So, c = 22
