Previous poster was very wrong, 5n-3=17 5n=20 n=4
n-5 is an expression, it cannot be a solution. Furthermore, there are infinitely many possible equations for which n = 5 could be a solution - even with the added requirements of the question.
If the question is, "What is the solution to 2n2 + 6n - 108 = 0 ?"The equation can be factored : 2n2 + 6n - 108 = (2n - 12)(n + 9) = 0If 2n -12 = 0 then n = 6If n + 9 = 0 then n = -9The roots of this equation are n = 6 and n = -9.
It's an equation in 'N' ... about the simplest one you could write.The solution of that equation is: N=0 .
N = 1
It is an algebraic equation which involves one unknown (n). This equation can be solved for n by adding 5 to each side: n - 5 = 12 → n - 5 + 5 = 12 + 5 → n = 17

I must change your description to read " ... 3 times as much as ... ".Then the equation is 0.33 N = 3 x (0.17 N) . The equation has no solution. That means that no numbercan make the equation a true statement.

The fact family of of the equation 12/N = 60 is: 12 = 60 N N = 0.2
N = 1
If there are n people, you have n*(n-1)/2 handshakes That gives the equation n*(n-1)/2 = 66 or n*(n-1) = 132 n2 - n - 132 = 0 (n - 12)*(n + 11) = 0 The solution to this quadratic are n = 12 or n = -11 Since the number of people cannot be negative, n must be 12.
You have one linear equation in two unknown variables: A and n. There can be no solution.
If you mean: -4*(n-6) = 12 then the value of n = 3
If you mean: 9n = 3 then the value of n is 1/3 which is the solution to the equation
