Simultaneous equations

[Priscila]

Hello,

I have a problem with simultaneous equations involved, so I made one of the variables level, but I do not need to integrate (add) the values over time. Is there any way to use a level variable without adding values?

Thanks

There isn't. If there's a simultaneity, there's generally a conceptual issue. Every feedback loop has to have a level somewhere; otherwise the state would be changing infinitely fast.
