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)
I will but the picture is blurry
N= -16.5
Subtract 33 then divide by 2
2n=-33
n=-33/2 or n=-16.5
ok is there more info about it
