Linearly varying force and bending moment problem.

I have attached both the question and my attempt at solution.

My problem is reducing the equation further to get the value of a/L

Have mercy on us. Rotate your phone when you take images of your work. It's very difficult to rotate the thumbnails and get a legible image. Good luck with your problem.

You can rotate it easily nah ...? What's the problem in rotating the image. If my work is not legible then just say, I'll repost it better than now.

Sorry, I tried downloading and viewing the thumbnails attached to the OP. Things just got worse after that. I'd like to help, but not at the cost of a sore neck.
