I am told to find the "Total heat capacity of the system in the Calorimeter"

All I have is this equation:
Csys=Ccal+Csol

What is this Csys? and how do I figure out how to use this equation?

Thankyou

It would have been nice if you had just posted the problem. As it is I'm working in the dark.

The Csys is the total and it's made up of the two components listed.
Ccal is the heat capacity of the calorimeter.
Csol is the heat capacity of the solution.
