Theres the circuit i have. Vdd = 10 V, Vtn = 2 V, Kn = .22 mA/V^2, Rg1 = 1.01 Mohm, Rg2 = 1.06 Mohm, Rd = 6kOhm, Rs = 5kOhm.

Im trying to figure out how to compute the drain current Id. As well as the drain voltage Vd and the source voltage Vs, but Id is priority.

Can anyone help?

[EDIT] I have figured out the gate voltage across the transistor to be 5.12077 V, therefore putting the transistor in saturation mode.

Does this link help?

You will have two simultaneous equations, I believe. The Vgs depends on the Id, which depends on Vgs.
