Although I just tried with the solve command and a random nonsolved equation. [V1  V2 = 10*Ix V1/j20 + (V1  V3)/20 + V2/10 + (V2  V3)/j10 = 0 V3/j10 + (V3V2)/j10 + 2<45deg + (V3  V1)/20 = 0 Ix = V3/j10] [V1 V2 V3 Ix] SOLVE as in https://www.youtube.com/watch?v=vj9K_bXKEY4 Can be used for system of complex equations, but I don't know the limits of the solve command, it seems to have odd pitfalls at times. One question is are the OP after a numerical solver with complex numbers as by definition (numerical) it should also do single equations with complex input. I haven't tested and I have no time just now to play it around to see if it is possible somehow. Edit. Yes, numerical solver do not like complex input and gives the "bad quess" error, I'm suprised actually.
