3n+18 = 39 -4n 3n+4n = 39 -18 7n = 21 n = 3

3n+6=18 n+2=6 n=4

n = 3 3n x 2 = 18 3n x 2 / 2 = 18 / 2 3n = 9 3n / 3 = 9 / 3 n = 3

3n-5=13 +5 +5 3n=18 /3 /3 n=6

3n = 0.138 n = 0.046

s = 9n - 18.

3n -5 = 19 3n = 19+5 3n = 24 n = 8

8 + 3(6) = 8 + 18 = 26

3n x 3n = 9n if 9n = 36 then n = 36/9 = 4

15-3n=n-1
