Do you mean this?

\(\displaystyle \frac{dy}{dx} = \frac{(H - By)}{A}\)

In the second part. I don't understand your differential equation.

Do you mean this?

\(\displaystyle \frac{dy}{dx} = \frac{H - By + B \ dy}{A}\)

I am sorry, but this is not a correct differential equation!

Yes, I indicated that the formulation was inadequate.

but you also mean that the equation proposed by you is not even a valid formulation? This can be easily rewritten to contain only one 'dy', so I don't see the problem.

The real problem is that the additional dy should not refer to 'x' but to 'x-A'. I don't know how to incorporate this.

What is the context of the problem? In other words, how did this problem arise - how was it formulated?Hi everyone,

I posted below question on mathforums.com half a year ago, but never got any reponse. So I hope someone can help me out here:

Show me how will you do it.Dear @nasi112

Please answer the question/s posed above.What is thecontextof the problem? In other words, how did this problem arise - how was itformulated?
