x is always +3 ahead (30-27=3)

and y is always trailing behind x by -3

Answer:

y = x - 3

Step-by-step explanation:

You are given an x and a y and need to find the difference.

Set up a formula using one of the given x and y pairs and solve.

y = x - u  plug in an x and y and solve for the unknown(u)

27 = 30 - u

-3 = -u

u = 3

Now plug the unknown into the original equation

y = x - 3
