Answer:

d = - 5.2

Explanation:

14.2 = - 1.4 - 3d

14.2 + 1.4 = - 3d

15.6 = - 3d

15.6/3 = - d

5.2 = - d

- d = 5.2

d = -5.2

Hope this helps.

Answer: d = -5.2

Starting equation:
14.2=-1.4-3d


\mathrm{Switch\:sides}:
-1.4-3d=14.2


\mathrm{Add\:}1.4\mathrm{\:to\:both\:sides}:
-1.4-3d+1.4=14.2+1.4


Simplify:
-3d=15.6


\mathrm{Divide\:both\:sides\:by\:}-3:
(-3d)/(-3)=(15.6)/(-3)

And your finial answer is: -5.2

--------------------------------------------

Have a great day and God bless! :)
