X - 3y = -8
x + 3y = 8
--------------- Add the equations
2x = =
x = 0
Plug zero back in to either equation and solve for y.
x - 3y = -8
0 - 3y = -8
-3y = -8
divide both sides by -3
y = 8/3
(0, 8/3)

Why?</h2>
Since we are given the margin of error and it's equal to ±0.1 feet, and we know the surveyed distance, we can calculate the maximum and minimum distance. We must remember that margin of errors usually involves and maximum and minimum margin of a measure, and it means that the real measure will not be greater or less than the values located at the margins.
We know that the surveyed distance is 1200 feet with a margin of error of ±0.1 feet, so, we can calculate the maximum and minimum distances that the reader could assume in the following way:
