1. 9x = 53 - 4y
2. 3y = 26 - 4x
If we multiply 1. by 3 we get:
3. 27x = 159 - 12y
If we re-order 2. to 4x = -3y + 26 and then multiply by 4 we get:
4. 16x = -12y + 104
If we now subtract 4. from 3. we get:
5. 11x = 55
Thus x = 55/11 = 5
Substituting x = 5 back into 1. gives:
45 = 53 - 4y
Thus
4y = 53 - 45
4y = 8
y = 8/4 = 2
Therfore our ordered pair written in the form (x, y) is (5, 2).
(0, 6)
The ordered pair is (6, 3).
The ordered pair is (3, 2).
The ordered pair is (2, 3).
13
The ordered pair is (1, 3).
There is no ordered pair for y =4. y=4 is a line, not a point.
5x=4y=-20 x=-4 y=-5 (-4,-5) is the ordered pair
(0, 6)
The ordered pair is (6, 3).
The ordered pair is (3, 2).
The ordered pair is (2, 3).
There are an infinite number of ordered pairs. (-5, -7) is one pair
The ordered pair is (5, 4).
The ordered pair is (-1, -2).
The ordered pair is (-1, -7).
The ordered pair is (1, 1).
