5 + n = 23 n = 18 18 - 5 = 13 ■
3n+6=18 n+2=6 n=4
-24
4n - 2n = 18 Therefore, 2n = 18 Therefore, n = 18/2 = 9
2 plus n is the true one, but 1 plus n is not?
n + 18 = 27 subtract 18 to 18 and 27 18-27=9 n = 9
n + 6 = 18 n = 12
9
n + 5 = 18 n = 13
3 + 9 = 12
N=3
N+18=30. Subtract 18 both sides N=12
5 + n = 23 n = 18 18 - 5 = 13 ■
n + 9 = 4747 - 9 = nTherefore n = 38.
you have 9n+17=-1 -17 -17 9n=-18 /9 /9 n= -2
3n+6=18 n+2=6 n=4
It is an equation and the value of n is 6
