Yah, at a basic, it’s V drop from the combined two resistors on each battery (the A and C points are irrelevant to this question, so add the two resistors together), then the “voltages in parallel” calculation for the B point.
Mind you, the 12V will discharge into the 9V and either or both might over heat.
