If f(x) = x + 8 and g(x) = -4x - 3, find (f-g)(x)

(f-g)(x) = 5x+11

Step-by-step explanation:

Given

as

(f-g)(x) = f(x) - g(x)

          = (x+8) - (-4x-3)

          = x+8+4x+3

          = 5x+11

Thus,

(f-g)(x) = 5x+11

idk

step-by-step explanation:

i don't know

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
