Answer 1

Answer:

d = 0

Step-by-step explanation:

cancel equal terms on both sides of the equation

= 8d = 6d

move variable to the left and change its sign

8d - 6d = 0

2d = 0

divide both sides of the equation by 2

d = 0

Answer 2

Answer:

d = 0

Step-by-step explanation:

-7 and -7 cancel out

8d = 6d

collect like terms 8d - 6d

8d-6d=0

2d = 0

divide both sides

d=0
