The expression "3n 6" is unclear without additional context. If you're looking for a solution to an equation, please provide an equation format (e.g., 3n = 6). However, if you meant to ask for the value of n when 3n = 6, then n would equal 2.
Let's give it a go:3n - 6 = 9Add 6 to each side of the equation:3n = 15Divide each side by 3:n = 5
3n + 6 = n + 202n = 14n = 7
3n + 6 = -9 Subtract 6 from both sides: 3n = -15 Divide both sides by 3: n = -5 Therefore n = -5
Let n be the number, then: 1/n - 1/3n = 1/6 Solve the subtraction on the left: 1/n - 1/3n = 3/3n - 1/3n = 2/3n But we know this is 1/6, thus: 2/3n = 1/6 ⇒ 3n = 12 ⇒ n = 4 Thus the number is 4.
9n+6-3n
6=3n or 3n=6
3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (4) = 3n + 6
A molecule with 3n-6 vibrational modes has a total of 3n-6 vibrational modes.
3n+6=18 n+2=6 n=4
3/5, 9/15, 12/20, 3n/5n for all n = 5, 6, 7, ...

Assume the expression is: 15 = 9 + 3n Subtract both sides by 9 to get: 15 - 9 = 9 - 9 + 3n 6 = 3n Finally, divide both sides by 3 to get: 6/3 = 3n/3 n = 2
