Answer:
(8, 63)
Step-by-step explanation:
The ordered pair is a solution to the equation when substituting the values for x and y make the equation a true statement.
If we let x represent the first number of the ordered pair, it will be a solution when ...
63 = 9x -9
7 = x -1 . . . . . . . divide by 9
8 = x . . . . . . . add 1
The blank gets filled with 8, so the ordered pair is (8, 63).
