$d=-3.8$
We need to get the d alone, so we cancel out the addition by subtracting 5.6 on both sides. This leaves us with the equation $-d=3.8$. We cancel out division using multiplication, so we multiply 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.
