Answer :

h=2f/m+1
subtract one from both sides
h-1=2f/m
multiply m to both sides
m*h-1=2f
divide 2 both sides
mh-1/2=F
(the whole left side of the equation is divided by 2 i just cant do it on the computer)

[tex]h = \frac{2f}{m} + 1 \\ \\ mh = 2f + 1 (re-arranged) \\ \\ mh - 1 = 2f \\ \\ f = \frac{(mh - 1)}{2} [/tex]
