Try to get the variables on the left and numbers on the right.
Subtract 6 to both sides.
6-4d-6=16-9d-6
-4d= 10-9d
-4d+9d=10-9d+9d
5d= 10
d=2

6 - 4d = 16 - 9d
-10 - 4d = -9d (subtracted 16 from both sides)
-10 = -5d (added 4d to both sides)
2 = d (divided both sides by 5)

6 - 4d = 16 - 9d, so, adding 9d to each side:
6 + 5d = 16, so, taking 6 from each side:
5d = 10, so
d = 2.
And it`s an equation.
Hope this helps, Twiggy.
