The answer is n + 1610.
23+n+5+n=23+5+n+n=28+2nIt depends what n is, once, you find out what n is equal to, plug it in to the equation above in bold.
So, 3 + 12 = n + 3. Subtract 3 from both sides of the equation and get 12 = n or n = 12 if you prefer.
14 ! If n=12, then 12-4 is 8, plus 6 is 14
There are three numbers. Their sum is 12-n + 12 + 12+n = 36 So their mean is 36/3 = 12.

23+n+5+n=23+5+n+n=28+2nIt depends what n is, once, you find out what n is equal to, plug it in to the equation above in bold.
So, 3 + 12 = n + 3. Subtract 3 from both sides of the equation and get 12 = n or n = 12 if you prefer.
If n + 7 = 12, then n = 12 - 7
14 ! If n=12, then 12-4 is 8, plus 6 is 14
If you mean: -3(n+5) = 12 then n works out as -9 because -3(-9+5) = 12
There are three numbers. Their sum is 12-n + 12 + 12+n = 36 So their mean is 36/3 = 12.
n=22 22 +12 34
6m + m + m + 4y + n + y + 12 + 2n Group like terms: 6m + m + m + 2n + n + 4y + y + 12 Add: 8m + 3n + 5y + 12
n3 + 8n2 + 12n = n(n+2)(n+6)
N=0.
12+123456789=123456801
n3 + 3n2 + 4n + 12 = (n3 + 3n2) + (4n + 12) = n2(n + 3) + 4(n + 3) = (n2 + 4)(n + 3).
