50. The function K(X) = 1.3X - 4.7 converts a man's shoe size in the United States to the equivalent shoe size in the United Kingdom. Determine the function K^-1(X) that can be used to convert a United Kingdom man's shoe size to its equivalent U.S. shoe size.
To find the inverse function:
1. Replace K(x) with y.
2. Switch the x and y.
3. Solve for y.



4. Replace y with K^-1(x)

Happy Calculating!!!
