14d-2d=-84 Add all terms if possible 12d=-84 Divide both sides by 12 d=-7
Hope this helps
First combine like terms: 14d+-2d=12d
Then do -84 divided by 12 = -7 D= -7
To solve for d in the equation 14 d − 2 d = − 84 , we combine like terms to get 12 d = − 84 . Dividing both sides by 12 gives us d = − 7 .
