so your equasion will be as follows:
B=Beta
G=Girlfriend
H=Hand
A=Answer
B-G+2H=A (solve for beta)
B=A+G-2H
Beta=Answer+Girlfriend-2 hands (Beta is equal to a girlfriend that has no hands.) "is what you are saying according to your statement above."
Don't stress out on this equasion because I didn't. lol.
