Answer :
Answer:
f = S + 6c - 8r /5
Step-by-step explanation:
When the question asks you to make f the subject it means that it wants us to show what f is equal to. So the end of our answer should start like this:
f =
So we want f by itself. Let's first remove the negatives in this question.
To do this we need to add 6x on both sides.
This gives us:
S + 6c = 5f + 8r
Now we want to take away 8r from S + 6c
This gives us=
S + 6c - 8r =5f
All that is left to do is to divide the left side by 5 because we want f left by itself.
This leaves us with=
S + 6c - 8r /5 = f
Remember that if you're writing this out that you are dividing ALL of the left side by 5 and not just the last few numbers if the left side
So the end result is
f= S + 6c - 8r /5
