Hi,

Could you please look at this problem in the picture and my steps?
(check my answer)

I do not have the solutions to the problem weirdly.

Hello, alingy1. Your work looks good to me.

As a check, think of the wall as a mirror and reflect the second part of the trajectory to the other side of the wall. Use this trick to reduce the problem to a more standard projectile problem.
 
TSny, could you be more specific about your technique? It sounds really interesting but I'm not sure how the number crunching goes.
 
See the attached figure. Can you find the horizontal range of the blue trajectory?
