Answer 1

Hello there!

To start off this problem, let's replace f(x) with x in the equation. This gives us the following.


`x= (3)/(4) x+12`

Subtract 3/4*x from both sides.


`x- (3)/(4) x=12`


`(4)/(4) x-(3)/(4)x=12`


`(1)/(4) x=12`

Now, multiply both sides by 4 to eliminate the fraction on the left side.


`x=12*4=48`

Your answer is B. Hope this helps! :)
