25 - 4(4) = 25 - 16 = 9.
3n + 2n = 25 5n = 25 n = 5
The value of n is 12.5
2n/3 = 4 2n = 3*4 2n = 12 n = 6 :)
2(4) = 8
25 - 4(4) = 25 - 16 = 9.
3n + 2n = 25 5n = 25 n = 5
2n-9=-4
The value of n is 12.5
2n/3 = 4 2n = 3*4 2n = 12 n = 6 :)
2(4) = 8
It is: 25+(2*13) = 51
n=4
Suppose the number is N. Then 2N - 4 = 47 2N = 51 N = 25.5
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
2n + 4 = 25
n = 1
