Hi, I would like to answer you question to help you out but unfortunately there is not enough information for me to do so. Maybe if you put a picture along with those words then I could solve the problem.
For example, when stating a problem such as 2 plus?= 4
Then I am able to solve by doing...
4-2=2
Check:
2 plus 2=4
But with your problem, F is perpendicular to line m whats blank
Then the only thing I am able to do is...
F=m
blank=?
Like I said I would love to help but I need a little more info than what is present now. Thanks.
Answer: 
Step-by-step explanation:
Add 
on both sides and subtract 
on both sides to leave x's on the left side and independent values on the right.
Solve the fractions.
Convert the mixed fraction 
to an improper fraction. You can do this by multiplying 1 times 35 and adding 2.
Now use the reciprocal (inverse fraction) and multiply on both sides to isolate x.
2 ,3,5,7,11,17,19,23,29,31, 37,41,43,47,53,59,61
67,71,73,79,83,89,97.....
