s = 9n - 18.
3n=n+10n3n=11n3n-3n=11n-3n0=8n0÷8=0÷8n0=n0 is the answer!!
That question has no answer since n must equal 3 and if you substitute n in 3n-2, you will see that it does not equal 3, it equals 7.
3n x 3n = 9n if 9n = 36 then n = 36/9 = 4
7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)
3n + 4n = -14 7n /7 = -14 /7 n = -2
3n + 2n = 25 5n = 25 n = 5
3n = 15 + 12 = 27, 27/3 = 9 = n
3n+1=7 3*2+1=7
s = 9n - 18.
3n=n+10n3n=11n3n-3n=11n-3n0=8n0÷8=0÷8n0=n0 is the answer!!
3n + 6 = n + 202n = 14n = 7
3n - 24 = 14 - 30n33n = 38n = 38/33
That question has no answer since n must equal 3 and if you substitute n in 3n-2, you will see that it does not equal 3, it equals 7.
3 + 3n = 9 + 2n + 4n n = -2
3n x 3n = 9n if 9n = 36 then n = 36/9 = 4
n=-9.6
