Question #8613f

Answer 1

`x = 8` in `ZZ_14`

Explanation:

In `ZZ_14`, we have `5*3 -= 15 -= 1+14 -= 1" (mod "14")"`

This shows that `5` is the multiplicative inverse of `3` in `ZZ_14`. Using that, we have

`3x-=10" (mod "14")"`

`=> 5*3x -= 5*10" (mod "14")"`

`=> x-=50-=8+3*14-=8" (mod "14")"`

Giving us our answer of `x = 8` in `ZZ_14`.
