The five, - one and 7 if used would give you a zero which you cannot divide by. Also in the problem, -3 would give you a zero and you would then no be able to do the problem either. You cannot multiply or divide by zero

7 and -1 are not allowable replacements because you would be dividing by zero, which is never allowed.
5 IS an allowable replacement.
