Hey there!
Here is your answer:
The proper answer to this question is option B "false".
Reason:
To solve for y in the equations y + 1/3 = 5/6, subtract 1/3 from both sides of the equation. This statement is false. In order to solve this you have to divide 1/3 on both sides.
Therefore the answer is option B.
If you need anymore help feel free to ask me!
Hope this helps!
