(9n - 8) should do it.
5*n + (n - 8) = 5n + n - 8 = 6n - 8
5/8 < n/6 6*5/8 < n ie n< 15/4 or 3.75
n - 5 = 8
n11 / n8 = n(11-8) = n3
22
n x n - 8

Well, honey, the product of 8 and n is simply 8n. It's as easy as that! So, if you need to find out what 8 times any number n is, just multiply them together and you've got your answer. Math can be a piece of cake when you break it down like that!
8-3/n
(9n - 8) should do it.
5*n + (n - 8) = 5n + n - 8 = 6n - 8

5/8 < n/6 6*5/8 < n ie n< 15/4 or 3.75
n+n+n=3n 3(8) = 24 24 columns
the equation is: (n / 8 ) - 5 = 9 the number is 112. 112 / 8 is 14 5 less than 14 is 9
