Answer
$d=-3.8$
Work Step by Step
We need to get d alone. Thus, we cancel out the addition by subtracting 5.6 on both sides. This leaves us with the equation $-d=3.8. $ In order to cancel out multiplication, we use division, so we divide both sides by -1 to get that $d=-3.8$. We plug -3.8 in for d and confirm that our answer is, indeed, correct.
