How can I rearrange equations to general form?

I have simplifyed example of my problem:

syms x y z

eqn1=x+y+5==-z

Matlab gives me answer (as it should)

eqn1=x+y+5==-z

But is there a command to rearrange the equation to either

eqn1=x+y+z+5=0

or

eqn1=x+y+z=-5

Thank you for your help.

Answer 1

[Dyuman Joshi]

Return all equivalent results with higher number of simplication steps

syms x y z 
eqn1=x+y+5==-z 

eqn1 = 

out=simplify(eqn1,'All',true,'Steps',4)

out =

This is what I was looking for, big thanks to you!

Answer 2

[John D'Errico]

syms x y z 
eqn1=x+y+5==-z

eqn1 = 

Nothing stops you from doing it yourself. For example, I might do:

eqn1 = eqn1 + z

eqn1 = 

Or, you can even use isolate.

eqn1 = isolate(eqn1,x+y+z)

eqn1 = 

Personally, I never understand these questions, though we see them often. :) All that has changed is where a term falls. It is still the same equation. A rose by any other name...

Firstly, thank you for quick respond.

I understand your point, and my example is bad, but the equations that I need to compute have often more variables and are more complicated. So solving them by hand can be a quite tedious process.

Another example:

syms a b c d e

eqn2=-12*a/34+b*24+c/12==d*23-12*e/5+345

I know I can solve this manually by doing just like you suggested:

eqn3=eqn2-23*d+(12*e)/5

And it gives the answer I need but I was just wondering if there was a simple command to automate this process for me.

Big thanks to you bothering to answer my silly questions :), really appreciate the help!
