Answer:
All real numbers are solutions to this equation
Step-by-step explanation:

<h3>
Answer:</h3>
there is no solution
<h3>
Step-by-step explanation:</h3>
Add 2y to the first equation and you get ...
x + 2y = 1
Compared to the second equation
x + 2y = 9
you find the equations are "inconsistent." That is, they describe parallel lines, so there are no values of x and y that satisfy both equations.
There is no solution.
