-14-8d = 2(6d+4)

-14-8d = 12d+8

Separate the variable terms and constants.

-12d-8d = 8+14

-20d = 22

Divide each side by negitive 20.

-20d/-20 = 22/-20

Solution d = -11/10.

Check:

-14-8(-11/10) = 2(6(-11/10)+4)

-14+44/5 = 2(-33/5+4)

(-70+44)/5 = 2(-33+20)/5

-26/5 = 2(-13)/5

-26/5 = -26/5.
