f-8-3f = 3-7f+4
f-3f+7f = 8+3+4
8f-3f = 15
5f = 15
f=15/5
f=3

put all f's on the left side, and numbers on the right side:
f -8 -3f = 3 -7f +4
f - 3f + 7f = 8 + 3 + 3 +4
simplify
5f = 15
isolate f
f = 15/5
f = 3

f-8-3f = 3-7f+4
all the fs go on one side and the numbers on the other
f-3f+7f = 8+3+4
5f = 15
divide both sides by 5 so 5f/5 = f
15/5=5
f = 5

Okay... for you goofs getting a faaaaaaar wrong answer....
F - 8 - 3F=3 - 7F + 4
You must simplify like terms, first.
-8 -2F=7 -7F
Now you have to isolate the variable... F So subtract 7 from each side.
-15 -2F= -7F
We're still isolating the variable F. So now add 2F to both sides.
-15= -5F
Their both negative, so you can make them positive by multiplying by negative one ( -1).
15= 5F
Now to make the F nice and simple... divide both sides by 5.
15/5 = 5F/5
What's that come out to?
3 = F
So there... and if you need to show work, I just did it for you.
