How do you find the answer to this equation: 3n equals 18
3n x 3n = 9n if 9n = 36 then n = 36/9 = 4
7
When n = 4, 3n = 3*4 = 12
In 3n-1 equals 11, n is 4.3n - 1 = 113n - 1 + 1 = 11 + 13n = 123n/3 = 12/3n = 4
How do you find the answer to this equation: 3n equals 18
3n -5 = 19 3n = 19+5 3n = 24 n = 8
3n x 3n = 9n if 9n = 36 then n = 36/9 = 4

15-3n=n-1
When n = 4, 3n = 3*4 = 12
3n = 618 n = 618 ÷ 3 n = 206
In 3n-1 equals 11, n is 4.3n - 1 = 113n - 1 + 1 = 11 + 13n = 123n/3 = 12/3n = 4
3n and n = 4? 3n ( the four replaces the n 3(4) = 12 =======
4n-8=3n+2 4n=3n+2+8 4n=3n+10 4n-3n+10 n=10 N = 10
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-11 = 19 3n = 19+11 3n = 30 Divide both sides of the equation by 3 to find the value of n: n = 10
