Answer:
No, it actually has infinite solutions.
Explanation:
2x+4y=22 is your 1st equation
-x-2y=-11 is your 2nd equation.
Let's say you want to cancel out the x variable. Multiply the 2nd equation by 2.
Then your equations would be:
2x+4y=22
-2x-4y=-22
If you add both you will get 0=0
Since both sides are equal to each other, there are infinite solutions.
