The basic rule of equations and formulae when rearranging terms is:-
What you do one one 'side' to eliminate a term must be done to the other 'side' to maintain the exact same result.
Your problem:- N= (B x A x F)/m (I've chosen B for ease in explanation - at this stage it does not really matter)
Your task - should you agree to accept it - is to make A the subject of the equation.
Let us concentrate on the Right Side (from now on known as RHS) of the expression
To eliminate m from RHS multiply by m
New interim expression is now
Nm = BAF
To eliminate B and F from RHS divide by BF
New interim expression
Nm/BF = A
Tidy up and restore terms
A = Nm/(Beta x F) (As you were required to do)
The constraints of this portal make difficulty for making very clear the mathematic operators ( x / )
I hope you can follow my explanation - keep on maths

any equation is simply a set of instructions so start with A and work away from it. So multiply it by Beta then by F b4 finally dividing by m which gives us our answer of N. Reversing this will give us our answer. So we multiply N by m followed by dividing by Beta and F giving us an answer of A :
Nm / BetaF = A

N = (Beta x A x F)/m
i)multiply both sides by m
mxN=(Beta x A x F)
ii)divide both sides by
Beta x F and change over
A= mxN/(Beta x F)
phew!

N x m gives
Nm=beta x A xF
devide by (beta x F)
so
(Nm) / (Beta x F)
leaving A=(Nm)/(Beta x F)

N = (Beta x A x F)/m
N x m = (Beta x A x F)
A = N x m / (Beta x F)

Im going to apply brackets to point what action you will possibly be able to desire to do X+2k=I -2k( ) -2k X=I-2k What you will possibly be able to desire to do to chop up the x is carry out the different function (inverse function) on the quantity you desire to eliminate. yet be sure you do it on the two aspects of the equals sign. desire I helped. If ou nonetheless are not getting it ask your instructor.

N = (B X A X F)/ M
NM = (B X A X F)
NM/BF = A
