Can anyone help me find nodevoltage equations for this circuit. The 10V power source is throwing me. Thanks.

There's only one unknown  the voltage V1. Call the bottom rail ground, then you only have to solve for V1 to know all the voltages and currents in the circuit. The V2 is just 10V, set by the voltage source on the right.lostinhere said:I have this much
Node 1: between the 25k resistor and the 11mA source)
node 2: between the 500 ohm resitor, 10v source, 1k resistor and 500 resistor and the 11mA source
V1: voltage across the 250 resistor
V2: voltage arcross the 1k resistor
reference node at the bottom of the pic
node1: (V120)/25K+V1/250+.011+(V1V2)/500=0
node2: .011+V2/1000+(V1V2)/500+......=0
I'm not quite sure how to hande the 10v supply.
