Question

What is the variable h in m = h-w/8?

Answer 1

For finding the h you should add +w/8 on both sides of the equation so you will have:
m + w/8 = h 
and that's the answer :))))
i hope this is helpful 
have a nice day 

Answer 2

So we want to solve for h
if it is
m=h-(w/8) then go to AAAAAAAAA
but if it is
m=(h-w)/8 then go to BBBBBBBB






AAAAAAAAAAAAAAAA
m=h-(w/8)
add w/8 to both sides
m+(w/8)=h



BBBBBBBBBBB

m=(h-w)/8
mulieplty both sides by 8
8m=h-w
add w to both sides
8m+w=h



so h=8m+w or h=m+(w/8) depending on where the h is
