using algebra, this can be written as 7(2N+2) 14n+14. 14 times the number plus 14.
N = the number It's [ 7N + (N+8) ]
666
It is: 13+x+7x or as 13+8x

Let the number be x and so if 8x +1 = 7x then x = -1
N = the number It's [ 7N + (N+8) ]
Let n be the number. Then what you're asking for is 6n+(n+7).
(3a-8) + 5x(a)
666
Five
Assuming the number is n; then: 2n + (6n + 5) = 8n + 5 That means five added to eight times the number
7x4+8
It is: 13+x+7x or as 13+8x
7x +9 = 6x
It is 63.
45
The sum, of the number of sides, is seven!
