18n + 27 or 9(2n + 3)

9 - 5n

3 + 3n = 9 + 2n + 4n n = -2

6n -3=2n+9 6n-2n=9+3 4n=12 n=12/4 n=3

6+5n=2n-9Isolate the variable by subtracting 2n and 6 from both sides.5n-2n=-9-63n=-15n=-5

'n' can be any number, but when applied to (2n + 4), n = 2.5

2n + 4m - 2n + m = 5m

3n + 9 = 3(n + 3)

2n plus 4 = 2n + 4

5n + 1 = 10 + 2n5n - 2n + 1 - 1 = 10 - 1 + 2n - 2n3n = 93n/3 = 9/3n = 3

9-2n = 7

4n

7+2n

5n = 2n + 3n .

Exactly that. 2n+2.

If you mean: (2n-14)(3n+9) = 0 then it is a quadratic equation whose solution is n = -3 or n = 7

It is 12n2 + 3n - 58

You can't. 17 + 2n = 21 + 2n gives: 2n = 4 + 2n which gives 0=4 which is not possible so the sum is not solveable.

(2n + 7)(2n + 7)

2n-9=-4

15m + (2n-6m) + 11m = = 15m + 11m + 2n - 6m = 26m - 6m + 2n = 20m + 2n = 2(10m + n)

9+2n=5n this is how you would set up the problem 9+2n-2n=5n-2n then you subtract the number with the variable on each side 9=3n this is what it leaves you with 9/3=3n/3 then you divide three by both sides to get the variable by itself 3=n then you have your answer Hope this helps you!!

That factors to (2n + 1)(n + 2)

5, 7, 9, 11 and 13

I'm assuming you are solving for n.2n + 6 = 7n - 9 {add nine to each side}2n + 15 = 7n { subtract 2n from each side}15 = 5n {divide each side by 5}3 = n
