See below.

Explanation:

You need to isolate #F# to solve. To do this, use the properties of mathematics (like the commutative property).

The setup would be like the following, I am not sure how you would like me to explain it more. What is important is that you do the opposite of the "Order of Operations", or PEMDAS backwards (in order to solve).

In case you don't know, PEMDAS is an acronym for:

P aretheses
E xponents
M ultiplication
D ivision
A ddition
S ubtraction

Okay, here it is:

#T=M(4+FG)#

#T/M = 4 + FG#

#T/M - 4 = FG#

Now, divide both sides by #G#.

#T/(MG) - 4/G = F#

Therefore, this is your answer:

#F=T/(MG) - 4/G #

I hope that helps!
