Engineering Node Voltage Circuit Analysis: Solving for V1, V2, and V3

[utnip123]

Hi, I am given a node voltage problem to find V1, V2, and V3 from this image below.

(v1+15)/20 + (v1-v2)/25 + (v3-v2)/50 + (v3 - 10)/10 = 0

18V1 - 12V2 + 24V3 = 50

V2: (v2-v1)/25 + v2/40 + (v2-v3)/50 = 0

17V2 - 8V1 - 4V3 = 0

15 = V3 - V1

Am I in the right track so far?

Your approach looks right.
