3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (4) = 3n + 6
Just plug in 30 for n in 3n-1. The answer is 89.
3n -5 = 19 3n = 19+5 3n = 24 n = 8
3n + 15 equals 3 times the number n, the answer to which is increased by 15. It can only be evaluated if the value of n is known. The expression can be factorised but that is of marginal help in evaluating it.
5m+2n, n-3m, 7-3n (5m+2n)+(n-3m)+(7-3n)=2m+7
The browser used by Answers.com for posting questions is rubbish. It rejects most mathematical symbols so all that we can see is 3n (274)(815)335 so there are no operators nor an equalitry or inequality symbol. There is, therefore, no equation or inequality and so nothing which can be used to find a value for n.

3n-11 = 19 3n = 19+11 3n = 30 Divide both sides of the equation by 3 to find the value of n: n = 10
-3(n-5)=24 -3n + 15 = 24 -3n= 24-15 -3n = 9 n=9/-3 n=-3
3n+8=a To find the value of n, you need to know the value of a.
3n+20=170 subtract 20 3n=150 divide by 3 n=50
Vertical angles are always equivalent. Therefore, we know that if the first vertical angle measures 30 degrees, the other must measure 30 degrees as well. So, since the second vertical angle has a value of 3n-6, we can set this equal to 30 degrees yielding the equation 3n - 6 = 30. From here, we just need to do some simple algebra: 3n - 6 = 30 3n = 36 n = 12 To find the value of n.
3n + 14 = 83n = 8 - 14 = -63n/3 = -6/3n = -2The value of n is -2.
How do you find the answer to this equation: 3n equals 18
A - B = -3n + 2 - (5n - 7) = -3n + 2 - 5n + 7 = 9 - 8n
The answer to -2(4+3n)=24 is:-5.33
(3n)(3n-1) = 3n * 3n - 3n * 1 Now, perform the multiplication: (3n * 3n) = 9n^2 (3n * 1) = 3n So, (3n)(3n-1) simplifies to: 9n^2 - 3n
