7n + 2 = 4n + 17Subtract 2 from each side:7n = 4n + 15Subtract 4n from each side:3n = 15Divide each side by 3:n = 5
3 + 3n = 9 + 2n + 4n n = -2

2 - 4N = 2 + 3NSubtract 2 from each side:-4N = 3NAdd 4N to each side:0 = 7NN = 0That's the only value of ' N ' for which the given equationcan become a true statement.
5n-2+2=4n 5n=4n n=0
4n-8=3n+2 4n=3n+2+8 4n=3n+10 4n-3n+10 n=10 N = 10
7n + 2 = 4n + 17Subtract 2 from each side:7n = 4n + 15Subtract 4n from each side:3n = 15Divide each side by 3:n = 5
3 + 3n = 9 + 2n + 4n n = -2

In the 4n plus 2 rule of Chemistry, the "n" stands for a whole number. This rule is used in organic chemistry to predict whether a planar ring molecule will exhibit aromatic properties based on the number of π (pi) electrons it has.

8n-2+4n = 66-5n 8n+4n+5n = 66+2 17n = 68 n = 4
If 7m = 4n+2 and 7m+2 = 8 m = 6/7 and n = 1
12+4n = 2n12+4n-4n = 2n-4n12 = -2n-1/2(12 = -2n)-6 = n
