Answer:
Step-by-step explanation:
Here we are given an equation in x and y and we are required to solve it for y
we have
subtracting 3x from each sides we get
now we divide both sides by 4 we get
Hence A) is our right answer.

(b)
For the experiment to be double-blind, the researchers who will evaluate the whiteness and interact with the subjects, and the subjects would not know which subjects received either the whitening gel or the placebo.
