The Electrician said:You're ignoring gneill's advice from post #43, where he said:
"Leave V3 as V3 for now! That way you don't have to carry around any complex digits through the initial simplifications. Don't be in a hurry to plug in numbers, especially complex numbers; That just gives more opportunities to make transcription and sign errors, and makes it more difficult to spot mistakes in the workings."
Is there any further you can go without starting to put the figures in?
##\frac{V_1}{Z_1} - \frac{V_{20}}{Z_1} - \frac{V_{20}}{Z_4} + \frac{V_3}{Z_5} - \frac{V_{20}}{Z_5} + \frac{V_2}{Z_3} - \frac{V_{20}}{Z_3} + \frac{V_3}{Z_3} = 0##
##\frac{V_1}{Z_1} + \frac{V_2}{Z_3} - \frac{V_{20}}{Z_1 + Z_3 + Z_4 + Z_5} + \frac{V_3}{Z_5 + Z_3} = 0##
