Answer:

d=-8.9

Step-by-step explanation:

Isolate the d variable.

-9.39 - 3.4d = -1.1d + 11.08

-9.39 -2.3d= 11.08

-2.3d= 20.47

d=-8.9

Answer:

d = -8.9

Step-by-step explanation:

-9.39 - 3.4d = -1.1d + 11.08

-9.39 = 3.4d -1.1d + 11.08

-9.39 = 2.3d + 11.08

-9.39 - 11.08 = 2.3d

-20.47 = 2.3d

d = -20.47/2.3

d = -8.9
