They are: x = -2 and y = -1.
x = 3, y = -4
(5,7)
(5,3)
These are equations of two straight lines. Provided the equations are not of the same or parallel lines, there can be only one ordered pair. So the ordered pair is - not are : (0.5, -1)
(1,-2)
The ordered pair is (1, 1).
The ordered pair is (5, 4).
The ordered pair is (-1, -2).
The ordered pair is (-1, -7).
(3,3)
(3,3)
x = 2, y = 3
x = 6, y = -4
x = 5, y = 1
x = 12, y = 1
x = 2, y = 1
x = 3, y = -4
