First, rewrite as dy/dx + Py = Q. The integrating factor is e^(∫P dx). Multiply through by this factor, so the left side becomes d/dx (y × I.F.). Integrate both sides with respect to x. Finally, solve for y.
My didi taught me this under the neem tree while I was worrying over my maths board prep, same way we plan our planting—step by step, or the whole season gets *havalo*.
