Answer
$d=-19/3$
Work Step by Step
We need to get d alone. In order to cancel out division, we use multiplication, so we multiply both sides by 2 to get that d+17=10 2/3. We now cancel out the addition by subtracting 17 on both sides, giving us a final answer of $d=-19/3$. We plug $-19/3$ in for d and confirm that our answer is, indeed, correct.
