I am designing a beam to replace a load bearing wall.

I have produced 2 separate UDL diagrams which, one for floor load and one for wall load. I am trying to find shear force and bending moment as in one for the total of the two diagrams. I know how to do it if the loads are spread across the whole beam but when just part of it is loaded, thats where im a bit confused.

thanks

Here is what i have so far attached:
