The function f(x) represents the time it takes a commuter to travel in the morning to work. The function g(x) represents the time it takes a commuter to travel in the evening from work.
Given f(x) = 5x − 7 and g(x) = 11x − 1, solve for (f + g)(x) to determine the total roundtrip time.

(f + g)(x) = 16x − 6
(f + g)(x) = 16x + 8
(f + g)(x) = 16x − 8
(f + g)(x) = 6x − 6
