IF the question means: What number, multiplied by 2, and reducing the answer by 9, gives a result that is greater than 11?
ANSWER: Any number greater than 10.
Let's try 11.
2 x 11 = 22.
22 - 9 = 13, which is greater than 11.
But if we try 10 ...
2 x 10 = 20.
20 - 9 = 11, but 11 is not greater than 11! So we need a higher number than 10.
Try it for yourself with ANY number greater than 10!

Alternative answer.
If the question means "What number decreased by 9, and then doubled, produces a number greater than 11?"...
... then work it out this way, working backwards:
What number is greater than 11?
We could say '12' is greater than 11.
Half of 12 is 6. Add 9 to 6 = 15.
So, now, let's try 15.
15 decreased by 9 is 6.
Twice that number is .... 12 (2 x 6), which is greater than 11!
But this would work for ANY number from 15 upwards!
15
100% equals the number. Less than 100% is less than the number. Greater than 100% is greater than the number.
7 greater than half a number
0.276 is greater than 0.275
Twice a number increased by eight is greater than negative four.
Six less than the product of 8
It's seven
any no. between 0&1 when raised to some power will obviously decreased.
The inequality that fits this condition is that X is greater than 1.
32 - 2x < 18
It is 5n - 8 <= 2n + 10
32-2x < 18
The number must be 42.
