5d-8d-4%3C=-4%2B3d

-3d-4%3C=-4%2B3d...........add 3d to both sides

-3d%2B3d-4%3C=-4%2B3d%2B3d

-cross%283d%29%2Bcross%283d%29-4%3C=-4%2B6d

-4%3C=-4%2B6d..........add 4 to both sides

-4%2B4%3C=-4%2B4%2B6d

0%3C=6d

0%3C=d
so, d is element of the set { 0,1,2,3.....}
or interval notation:
[0,infinity)
