    My working out is in the attachment (thought it would be easier). If everything is right, then the only thing I'm not sure about is the last bit and how to get the final answer.

    'Find the general solution of the differential equation:
    dy/dx=3x+y+1/(y-x-3)

    I don't understand your working.

    I just solved this using a substitution.

    u=y-x-3
