I have a question about a particular reaction mechanism! The reactants and products are already put down for me; my task is to draw the arrows for the mechanism.

I believe that it is just an addition reaction with 3-methyl-cyclohexene and HBr. However, the Br ends up being on the same carbon as the methyl group. I thought that the Br should go to the carbon with the positive charge. I do not understand how this is the product.I am wondering if this is even an addition reaction, or if its SN1, SN2, E1 or E2enter image description here
