Reorder the terms:
-5 + 2d = 17
Solving
-5 + 2d = 17
Solving for variable 'd'.
Move all terms containing d to the left, all other terms to the right.
Add '5' to each side of the equation.
-5 + 5 + 2d = 17 + 5
Combine like terms: -5 + 5 = 0
0 + 2d = 17 + 5
2d = 17 + 5
Combine like terms: 17 + 5 = 22
2d = 22
Divide each side by '2'.
d = 11
