Answer:
Variable measured in the Ordinal scale
Step-by-step explanation:
An ordinal scale is a scale (of measurement) that uses labels to classify cases (measurements) into ordered classes. Note that an ordinal scale implies that the classes must be put into an order such that each case in one class is considered greater than (or less than) every case in another class as seen in the question.

Answer:
(x, y) = (7, -1)
Step-by-step explanation:
The expression for x makes it easy to use that for substitution.
3(-7y) +y = 20
-20y = 20 . . . . . collect terms
y = -1 . . . . . . . . . divide by -20
-7(-1) = x = 7 . . . use y in the second equation to find x
The solution is (x, y) = (7, -1).
