# Need help figuring out limits of double integral

1. The problem statement, all variables and given/known data
Apply Green's Theorem to evaluate this integral:

Integral of: (6y + x) dx + (y + 2x) dy
over the curve C, where C is: The circle (x - 2)^2 + (y - 3)^2 = 4

2. Relevant equations

3. The attempt at a solution
To use Green's Theorem for this I would need to figure out the x and y limits of integration. With order of integration dx dy, I can see that 1 <= y <= 5. However I can't seem to figure out what the x limits would be. I've done similar problems except with a simpler circle centered at origin, so I'm sure this can't be that much more complicated..I'm just not getting it for some reason. Any suggestions?

Well you have the equation of the circle. Use that to find an expression for x.
