For this, plug in x for both of the equations (so you don't do anything because that is how it is written) and then you add them. X-13

x - 1

Step-by-step explanation:

(f + g) (x) = f (x) + g (x)

(f + g) (x) = (3x - 7) + (-2x - 6)

(f + g) (x) = 3x - 7 - 2x + 6

(f + g) (x) = 3x - 2x - 7 + 6

(f + g) (x) = x - 1
