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

Subtract 3/4*x from both sides.



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

Your answer is B. Hope this helps! :)
The answer to 9- (-6) is 15
Answer:


Step-by-step explanation:
Let's solve for x.

Step 1: Add -6y to both sides.
11x+6y+−6y=−22+−6y
11x=−6y−22
Step 2: Divide both sides by 11.


Let's solve for y.
11x+6y=−22
Step 1: Add -11x to both sides.
11x+6y+−11x=−22+−11x
6y=−11x−22
Step 2: Divide both sides by 6.
