to figure out if 2,2 is a solution of the system, you have to plug the value of 2 in for both x and y in the system, and solve to see if it comes out or not...
If you provide the system I can definitely help you out more specifically!
here this might help though, to figure out if (2,2) is a solution of the system you would have to plug 2 in for both x&y in the system, then you will see (after solving) if its a solution or not :)
