1.x%2B9y=5
2.x=6-9y
Use the substitution method.
Substitute eq. 2 directly into eq. 1 for x and find y.
%286-9y%29%2B9y=5
6=5
Your equations lead to an inconsistency.
There is no solution.
These are two parallel lines that never meet, so there is no intersection (solution).

To type an ordered pair means to give the answer in the form of a point (x,y).

The ordered pairs are the letters x and y in the point (x,y).


Understand?


x+9y = 5...EQUATION A
x = 6-9y...EQUATION B


As you can see, EQUATION B tells us that we can replace x in EQUATION A with
6 - 9y to see if we can solve for y.


x+9y = 5...EQUATION A


Let x = 6 - 9y and solve for y.


6 - 9y + 9y = 5


I see a problem right away!!


Notice that both y letters (one is positive and the other negative) cancel each other out leaving us with 6 = 5 which makes no sense.


Right away I know that this system of linear equations has NO SOLUTION.


Since there is no solution, we cannot give x and y a value in the point (x,y).


FINAL ANSWER: NO SOLUTION
