Hi all,

I was trying to solve a problem but I found a difficulty, which I summarize in an example:

Good behaviour:
```define f2(x,y)=4x+2y+1
done
solve(f2(x,y)=0, x)
{x=((-y)/(2))-((1)/(4))}```
```define f1(t)=4x(t)+2y(t)+1
done
solve(f1(t)=0,x(t))
Shouldn't it result in sth like:
`{x(t)=((-y(t))/(2))-((1)/(4))}`
?

Thank you.

Hi.
I think SOLVE function can solve an equation with exact variable (like x) not for a function. you can use

You should first define x(t), then f(t) and use Solve(Expane(f(t))=0, t)
