3n + 2n = 25 5n = 25 n = 5

The question seems ambigous, but I will consider n 2n to be solving for n:2n - 3n = n/3 + 14-n = n/3 + 14-3n = n + 42-4n = 42Thus, the solution is n = -42/4 = -21/2 = -10.5.
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
5n + 7 = 28 + 2n (-2n) 3n + 7 = 28 (-7) 3n = 21 therefore, n = 7
3n + 2n = 25 5n = 25 n = 5
3 + 3n = 9 + 2n + 4n n = -2
7-2n=n-147-2n+2n=n-14+2n7=3n-147+14=3n21=3n21/3=3n/37=n
The question seems ambigous, but I will consider n 2n to be solving for n:2n - 3n = n/3 + 14-n = n/3 + 14-3n = n + 42-4n = 42Thus, the solution is n = -42/4 = -21/2 = -10.5.
5n = 2n + 3n .
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
Well, isn't that a happy little equation we have here! To solve 3n - 2n, all you need to do is subtract 2n from 3n, which leaves you with n. So, the answer is simply n, a beautiful and peaceful solution. Just like painting a serene landscape, sometimes the simplest answers can bring the most joy.
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
n=-9.6
5n + 12 = 3n Try to get all expressions with n on the left side 5n + 12 - 3n = 3n - 3n 2n + 12 = 0 Try to get rid of 12 on the left side 2n + 12 - 12 = -12 2n = -12 n = -12/2 = -6
2n+3n+7=-41
