Commutative
no
The value of n is 3, by the commutative property.
No. If your trying to find n, then you subtract four from each side. n = 10 That would be subtraction property of equality.

No property. Unless n is known there is no property exhibited.
No. If your trying to find n, then you subtract four from each side. n = 10 That would be subtraction property of equality.
It is the additive identity property of zero. (n+0=n)
9n+9=81 9n=72 n=8
8n = 72 n = 72 / 8 n = 9
5
N=72
n/18 = -72 we can solve for n by multiplying both sides by 18 which shows n = (-72)(18) = -1296
n = 8
