no. only elena is correct
explanation: in order to solve the equation you first need to subtract 2d from both sides so it’ll look like this
8d-2d = 2d-2d
then you need to combine like terms (the new terms you added are both negative so it cancels out the right side) and it’ll look like this
6d = 0
finally, to find d, divide both sides by 6 because its being multiplied by d
6d/6 = 0/6
zero divided by anything is zero so you are left with:
d = 0
