4n - 2n = 84 2n = 84 n = 42
3n + 2n = 25 5n = 25 n = 5
The value of n is 12.5
Nonsense.
-7 = 2n + 19 Subtract 19 from both side -26 = 2n Divide by 2 on both sides n = -13
It is: 2n^2 -5n -42 equals (2n+7)(n-6) when factored
4n - 2n = 84 2n = 84 n = 42
4n - 2n = 18 Therefore, 2n = 18 Therefore, n = 18/2 = 9
If: -6n-2n = 16 Then: n = -2
If: 2n = 1 Then: n = 1/2 or 0.5
Suppose the number is N. Then 2N - 4 = 47 2N = 51 N = 25.5
Seventeen minus three equals ?
3n + 2n = 25 5n = 25 n = 5
The value of n is 12.5
2n+2n equals 4n
Nonsense.
2n plus 7 equals 19 2n equals 12 n equals 6
