Answer:

d = -10

Step-by-step explanation:

(d is the variable)

-6d - 10 = 10 - 4d

+4d        +10

-2d = 20

-2d/-2    20/-2

d = -10

:)

Answer:

d = 2

Step-by-step explanation:

Simplify both sides.

6d − 10 = 10 − 4d

6d + −10 = 10 + −4d

6d − 10 = −4d + 10

6d − 10 + 4d = −4d + 10 + 4d

10d − 10 = 10

10d − 10 + 10 = 10 + 10

10d = 20

20 ÷ 10 = 2
