system of differential equations

Consider the system of first-order differential equations:

Identify the two nullclines of this system, and find the two equilibrium solution coordinates.

I found the vertical nullcline to be and the horizontal to be

And I know equilibrium solutions are when both vertical and horizontal null clines are zero...but how exactly do I solve for that? Do I just set the two null clines equal to each other...? Any help is greatly appreciated!
