Respuesta :

First you divide which gives you 3 then you subtract 42-3 which gives you 39 the you add 3 the answer is 42 PEMDAS
please mark me brainiest you have to do division first so that would be 3
so 42 - 3 + 3 so now you have to do addition so 3 + 3=6  so 42 - 6=36
                      so your answer is 36
