5f + 4s is your answer

hope this helps

add numbers with same variables together.

Answer 2

So what you can do first is reorder the terms, to:

3f + 2f + 4s

So that like terms are next to each other.

Now, you can just add 3f with 2f, like a normal addition problem, to get:

5f + 4s

That would be an equivalent expression.
