Reasoning:
The rule says if you know what x is, divide by 2 to get y
In the first row, if x = 8, then y = x/2 = 8/2 = 4.
In the second row, x = 14 leads to y = 7 since 14/2 = 7.
The third row has us go in reverse. We multiply the y value by 2 to find x
This is because y = x/2 solves to x = 2y. So if y = 3, then x = 2y = 2*3 = 6.
We can then check this to get y = x/2 = 6/2 = 3.
