H (x) = 3x-5

g (x) = -3x-1

Find (h-g) (x)

(h-g) (x) =

Taking h (x) and g (x) and algebraically subtracting them

3x-5 - (-3x-1)

if it makes it easier distribute the negative to get

3x-5+3x+1

Combine like terms to get

(h-g) (x) = 6x-4

Make x any value needed if you need to go further with the same equation
