Plz help need this! pic in bottom!

Answer 1

Ok so you subtract 8 from both sides and you get

13d = -9

Then you need to get d by itself
So divide both sides by 13

The answer should be about -0.69

d = -0.69

Answer 2

Explanation:

13d + 8 = -1

subtract 8 from both sides

13d = -9

d = -9/13

either keep it in fraction form or if you divide it out it is -0.6923
