Answer

$d=-6.33$

Work Step by Step

We need to get the d alone. We need to use multiplication to cancel out division, so we multiply both sides by 2 to get that d+17=10.667. We now cancel out the addition by subtracting 17 on both sides, giving us a final answer of d=-6.33. We plug -6.33 in for d and confirm that our answer is, indeed, correct.
