I simply would like to isloate a variable from an expression/equation, e.g.:

```
using ModelingToolkit
@variables a b c
eqs = 0 ~ a + b + c
```

I want to solve this for variable ‘a’ (isolate ‘a’ on the left hand side).

As I understand, Modeling Toolkit is mainly intended for coupling of symbolic and numeric math and optimize the latter. However, I would like to use it for this kind of (or more complicated) equation solving instead of doing it by hand.

Thanks!
