Homework Statement

Find Q point of a BJT transistor

Relevant Equations

Q(Ib,Ic,Ube,Uce), Ube=0.7V

Hello,

I need help with this bjt transistor and finding the Q point. The problem I have is that I don't know how to do the thevenin theorem on this one. If someone could help me and show me how its done that would be great. Thank you!
The transistor looks like this on the picture:

This is my attempt at doing it but don't know if its correct:
