Alright, that's what I thought, I just wanted to make sure. I'm not really all that confident in myself when it comes to math lol

nnesha · Answer

$$\huge\rm \color{Red}{g(x)}=2(x-4)$$$$\huge\rm \color{Red}{20}=2(x-4)$$
now solve for x

anonymous · Answer

x = 14

nnesha · Answer

thats mean you're pretty good at math :=)

nnesha · Answer

yes right you can check ur answer 
substitute x for 14 $$20=2(\color{red}{14}-4)$$
