n = 3

3n x 2 = 18

3n x 2 / 2 = 18 / 2

3n = 9

3n / 3 = 9 / 3

n = 3

Q: What is n in 3n times 2 equals 18?

3n - 2 = -10 3n = -10+2 = -8 n = -8/3 or -22/3

-3n + 4 = 2Subtract 4 from each side ==> -3n = -2Divide each side by -3 ==> n = 2/3

If n is 2, then 3n plus 1 would equal 7.

10n+2

1 x 18 = 2 x 9 = 3 x 6 = 18

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

3n - 2 = -10 3n = -10+2 = -8 n = -8/3 or -22/3

perimeter equals 2 times width plus 2 times length so, perimeter equals 2(3n+2)+2(n-1) = 6n+6+2n-2 = 8n+4.

3n^2

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.

7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)

It is: 2 times 18 = 36

18 - 3n + 2 = n + 20 - 4n gather terms together on both sides of equation - 3n + 20 = - 3n + 20 0 = 0 =============no true solution here Actually, it's an infinite number, not "no solution" because it can also be done to end with n=n. I realize you didn't strictly say "no solution" but that's what it sounds like, so I'm just clarifying. -3n+20=-3n+20 -3n=-3n n=n

-3n + 4 = 2Subtract 4 from each side ==> -3n = -2Divide each side by -3 ==> n = 2/3

5-2=3n=3

If n is 2, then 3n plus 1 would equal 7.
