Please look at the attachment. Why didn't I get the supposed answer 101,4=8,6 V? Is this formula wrong? Why doesn't this formula work?

Your circuit simulation tool is using a transistor model that is not consistent with a typical silicon bipolar transistor. It's not even close and behaves more like a germanium transistor. Probably the saturation current is wrong in the model. Also, your assumption of Vbe equal to 0.7 is just an approximation.Why didn't I get the supposed answer 101,4=8,6 V? Is this formula wrong?
