# Step-by-step solution of a system of symbolic equations - Call Wolfram Alpha in Mathematica

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.

WolframAlpha appears to be pretty consistently confused by multicharacter variable names, and sometimes even by single character names.

This appears to work

WolframAlpha["solve {-a*b=Z*c+d,e/f=b+g,h*g+Z*i+Z*j+k=0,i=j+c,-d-Z*c+Z*j+k=0} for {b,j,c,i,g}"]


but doesn't include your PodStates which you try to put back in and get that correct.

• Hello @Bill, I need step-by-step solution; run my second code please. Jul 21, 2018 at 16:00
• I understand what you want/need. I tried over and over and over and over to get "Podstates" to work and I simply failed. I tried your code, I tried other SE examples, I simply failed. But I did show you how to get WolframAlpha to understand and solve your system. And I left it up to you to insert your "Podstates" and get it working, apparently you are better at that than I am. So I hope you are able to complete that last step.

• Hello @Bill, finally I found the solution also thanks to your reply: WolframAlpha["{-ab=Zc+d,e/f=b+g,hg+Zi+Zj+k=0,i=j+c,-d-Zc+Z*j+k=\ 0} for {b,j,c,i,g}", PodStates -> {"Solution__Step-by-step solution"}] Jul 29, 2018 at 17:44
