To solve for f, we need to get f by itself. To do this, we need to move all the numbers to one side of the equation, and all the variables to the other
-f+2+4f=8-3f
Combine like terms
(-f+4f) +2=8-3f
3f+2=8-3f
Add 3f to both sides
3f+3f+2=8-3f+3f
6f+2=8
Subtract 2 from both sides
6f+2-2=8-2
6f=6
Now all the numbers are one sides, and the variables are on the other. f is still not completely by itself, it is still being multiplied by 6. To reverse this, divide both sides by 5
