You need to isolate the variable...which means get all the letters on one side, and all the numbers on the other side of the equal sign. So...you add 8 to both sides, and subtract 2d from both sides...
8d-4d-6d-8=2d =>8d-4d-6d-2d-8+8=2d-2d+8
8d-4d-6d-2d=8 => -4d=8
Now you must divide both sides by -4.
-4d=8 => -4d/-4=8/-4
d=-2...voila your answer is d=-2. Wasn't that fun?

8d - 4d - 6d - 8 = 2d
Visualize (8 - 4 - 6 = -2)
-2d - 8 = 2d
+2d +2d
- 8 = 4d
Divide both sides by 4.
-2 = d

8d-4d-6d-8=2d ( shift all the numbers having d to right side)
-8= 4d+6d+2d - 8d (so, +8d becomes -8d and the rest remains the same)
-8= 12d-8d (subtraction)
-8=4d (divide 4 on left side keeping d on the right)
d= -2

(8d-4d-6d) - 8 = 2d
8-4-6 (d) -8 =2d
-2d -8 = 2d ... subtract 2d from each side -2d -2d-8 =2d-2d
-4d-8=0 ... add 8 to each side
-4d-8+8=0+8
-4d=8 ... divide both sides by -4
-4d/-4 = -8/4
d = -2

8d-4d-6d-8=2d
swap sides with 'em here.
8d-4d-6d-2d=8
add the left side
-4d=8
divide
d=-2
