Solving rational expressions, equations, and functions

Revenue, cost, and profit are studied in economics. If R(x) is a revenue function and C(x) is a cost function, then the profit function, P(x) is equal to: P(x) = R(x) – C(x)

Where x is the number of items manufactured and sold by a company.

A company builds and sells six products each week; assume that:

R(x) = (6x-7)/(x+2) and C(x) = (4x-13)/(x+3). Determine the profit function.
