Plz solve question 12

C

Step-by-step explanation:

To solve for 12, we can use eliminate or substituion to solve our system of equations. Let's use elimination method.

Let's add the equations together. This way, 3f+(-3f)=0

                  [divide both sides by -4]

Now that we know k, we can plug it into either equation to find f.

       [multiply]

            [subtract both sides by 12]

                   [divide both sides by 3]

Now that we have f and k, we know that C is the correct answer.

first one is a: renaming a fraction. second one is c: de-c
