y'=e^x/(cos(y)+1)

I would really appreciate the help, especially if someone can tell me if it is possible at all to eliminate y from the equation, and how I can work that out.

That is the correct result. And no, you cannot eliminate y from the expression.

However, you can take any point (x,y) = (3,4) for example, and plug it into the equation to get the instantaneous slope at that very point. Then you can use that slope to write an equation for the line tangent to y(x) at (3,4).
