Translate the phrase into an algebraic expression:

the quotient of `k` and the difference of `b` and `x`

Hint: You may need to use parentheses to define the numerator and denominator, such as `(2+2)/(2+2)` = (2+2)/(2+2).

Box 1: Enter your answer as an expression. Example: 3x^2+1, x/5, (a+b)/c
Be sure your variables match those in the question
