What’s wrong with the next reasoning that supposedly proves that the equation x−1=0 has no solutions? Starting with the equation x−1=0, divide both sides by x−1: x−1=0,1x−1/x−1> 0/x−1,1>0
a) Dividing by x−1 is not a valid operation
b) The proof does not consider all possible values of x
c) The conclusion drawn does not logically follow from the steps taken
d) x−1 can never be equal to 0
