7/8s + 8 = s - 1/8
Multiply both sides of the equation by 8
8(7/8s) + 8(8) = 8(s) - 8(1/8)
7s + 64 = 8s - 1
Transpose 7s
7s + 64 - 7s = 8s - 1 - 7s
Collect like terms
64 = s - 1
Transpose 1
64 + 1 = s - 1 + 1
Collect like terms
65 = s
The answer is 65
- - - - - - -s-

7/8s + 8=s-1/8
7/8s-s=-1/8-8
7s-8s/8=-1-64/8
-s/8=-65/8
- and 8 cut each other
s=65

ans = 65
7/8s + 8 = s - 1/8
7/8s + 8 (and) 1/8 = s
8 (and) 1/8 = 1/8s
65/8 = 1/8 s
8(65/8) = s
65 = s

7/8s+8=s-1/8
7/8s-s=-1/8-8
-1/8s=-81/8
1/8s=81/8
1/8s=65/8
Multiply both sides by 8,
s=65

7/8s+8=s-1/8
=(7+64s)/8s=(8s-1)/8
=[7+64s]8=[8s-1]8s
=56+512s=64s^2-8s
=64^2-520s-56=0
=8s^2-65s-7=0
