Question

If (n-3)! = 42 * (2n-4)! Then find n?

Answer 1

This does not appear to have a solution.

Explanation:

Are you sure that you have written this correctly? Valid arguments for the factorial function are integers greater than -1. `n=3` is the first integer that provides a valid argument, but

`42*(2n-4)!>(n-3)!`

for all `n>=3`.
