Question

Solve for f: 6f + 9g = 3g + f

Answer 1

-6g/5 that would be the answer . This is how i got it.
6f+9g=3g+f
5f+9g=3g
5f=-6g

Answer 2

6f+9g=3g+f

Step 1: Add -f to both sides.

6f+9g+−f=f+3g+−f

5f+9g=3g

Step 2: Add -9g to both sides.

5f+9g+−9g=3g+−9g

5f=−6g

Step 3: Divide both sides by 5.

5f/5=−6g/5

f=−6/5g
