Hello everyone, I'm trying to get a step-by-step solution of a system of symbolic equations:

WolframAlpha["{-R3*IR3=Z*I2+VWE2,VIN/R4=IR3+IC3,ZC3*IC3+Z*I3+Z*I1+\
VWE1=0,I3=I1+I2,-VWE2-Z*I2+Z*I1+VWE1=0},{IR3,I1,I2,I3,IC3}", 
PodStates -> {"Solution__Step-by-step solution"}]

The above code does not work; instead if I have a system of numeric equations, it works:

WolframAlpha["x+y+z=1,x+3y-5z=3,14y-5z=0", 
 PodStates -> {"Solution__Step-by-step solution"}]

The problem is how specify the unknowns.

Thank you for your help.
