Answer:
second option
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = x - 9 ( add 9 to both sides
y + 9 = x
Change y back into terms of x with x = (x) , then
(x) = x + 9
If 3c+4d=2 then c=(2-4d)/3
And if you put that into the other equation
Then you multiply everything by 3, getting
And then

I dont have a calc with me right now but you just pot this into the calculator:
And when you get the number you insert it into the nest eqation to get c
So basically
