I am having trouble find the inverse.
Hello, dwsmith!
I am having trouble find the inverse.
No wonder . . . it doesn't exist.
Suppose a solution exists . . .
We have: .
This means: .
Solve for
Since is an integer, must be a multiple of 12.
This means: .
Solve for
And we see that is not an integer.
. . Therefore, there is no solution.
