Answer
d=2 6/7
Work Step by Step
We first combine like terms to obtain that $-14d+76=36$. We need to get the d alone, so we cancel out the addition by subtracting 76 on both sides. This leaves us with the equation $-14d=-40$. We cancel out multiplication by using division, so we divide both sides of the equation by -14 to get that d=2 6/7.We plug 2 6/7 in for d and confirm that our answer is, indeed, correct.
