Twice a number decreased by 9 is greater than 11 what is the number?

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!
