11 5 more than six is the same as saying 5+6
It is: 2x+11 = -1 and the vaue of x works out as -6
11
So a number is composite if it has more ways to be divided than by itself and 1. So for example 11 is prime because it can only be divided 11/1 or 11/11. But six can be divided in half because 6/2 =3 not a number with a decimal

y = 6 * ( x + 11)
11 5 more than six is the same as saying 5+6
The expression appears to be: 6/n +11
what is 6 more than 2
It is: 2x+11 = -1 and the vaue of x works out as -6
11
The factors of 11 are 1 and 11. Neither is one more than a multiple of 6.

z is the number. I think the question might be ".. 7 times the number...? So 63+7z =11z-6 or 4z=57 or z=57/4 . If not, please be more specific.

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!
