Question

To solve the equation 8d = 2d . Lin divides each side by 2d, and Elena subtracts 2d from each

Answer 1

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
