Question

I need help in everything

Answer 1

the first thing you do is subtract 13 from both sides. you end up with -6f=2f-24.
then you subtract 2f from both sides. you end up with -6f-2f=-24 or -8f=-24.
then you divide -8 from both sides. you get f=3. I hope I helped.

Answer 2

-6f+13=2f-11
-6f - 2f = -11 - 13
-8f = -24
f = 3
