??? NO! A vertical nullcline is when dx/dt= 0 which means 1- x- y= 0. Was that a typo?

No, don't set them equal to each other, set them equal to 0! What values of x and y satisfy both 1- x- y= 0 and ?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!
