I understand their method. However, if you use the node to the left of the 2 ohm resistor (the node where the voltage = 75 V) then you get:

(75-Vx)/2 -10 = 0

so 75-Vx = 20

so Vx - 75 = -20

Vx = 55 V

But this is not 25 V as it should be?

When doing nodal analysis, do you have to consider each node?
