7/8h - 5/8 = 2
8(7/8h) - 8(5/8) = 8(2)
7h - 5 = 16
7h - 5 + 5 = 16 + 5
7h = 21
7h / 7 = 21 / 7
h = 21 / 7
h = 3

7/8 h = 2 + 5/8
7/8 h= (16 + 5)/8
h = 21/7 = 3

I can't tell if you mean 7/(8h) - 5/8 = 2, or (7/8)h - 5/8 = 2, or even 7 / (8h - 5/8) = 2. So I'll just assume the second one is true.
(7/8)h - 5/8 = 2
(7h/8) - 5/8 = 2
(7h - 5)/8 = 2
(7h - 5) = 16
7h = 21
h = 3

7/8h-5/8=2
multiply by 8
7h -5 = 16
7h = 21
h = 3

Since you probably mean (7/8)h - 5/8 = 2, you should start by multiplying both sides by 8 to get rid of the fractions.
7h - 5 = 16
7h = 21 ---> Add 5 to both sides.
h = 3 ---> Divide bother sides by 7 to get h alone.
Check solution:
(7/8)h - 5/8 = 2
7/8(3) - 5/8 = 2
2 5/8 - 5/8 = 2
2 = 2
Yep, it works.
h = 3

(7 / 8)h - 5/8 = 2
(7 / 8)h = 21/8
h = 3
OR it could mean
7/(8h) - 5/8 = 2
7/(8h) = 21 / 8
7 = 8h(21 / 8)
8 / 3 = 8h
h = 1 / 3

(7/8h)-(5/8)=2
Multiplying both members by (8h):
7 - 5h = 16h
21h = 7
h = (1/3)
Right?!!?

7/8h-5/8=2
Multiply both sides by 8:
7/h - 5 = 16
Multiply both sides by h:
7 - 5h = 16h
Add 5h to both sides:
7 = 21h
Dividing both sides by 7 shows that h = 3.
