00:01 For this exercise, we have y equal to x over 11, and we're going to substitute these in order to determine if they are inverses of each other or if they are not inverses of each other.
00:18 So you have x equal to y over 11, and now we're going to multiply both sides by 11, such that y is by itself, and that equals 11x...
