Answer 1

Hello there!

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

$x= \dfrac{3}{4} x+12$

Subtract 3/4*x from both sides.

$x- \dfrac{3}{4} x=12$

$\dfrac{4}{4} x-\dfrac{3}{4}x=12$

$\dfrac{1}{4} x=12$

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! :)
