3n + 2n = 25 5n = 25 n = 5
6+n = 2n+5
5-2n=3 -2n=3-5 -2n=-2 n=1
When n=53, then 2n + 1 = 107
The value of n is 12.5
3n + 2n = 25 5n = 25 n = 5
If: 2n = 1 Then: n = 1/2 or 0.5
6+n = 2n+5
2n plus 5 n would be 7n and its impossible to solve the value of n.
5-2n=3 -2n=3-5 -2n=-2 n=1
If you mean: 2n = 5-2 then n = 1.5
If: -6n-2n = 16 Then: n = -2
When n=53, then 2n + 1 = 107
40n2 + 40n = 40n(n + 1) ------------------ That is as factored as far I can see it being factored.
Solve for n. 6 = 1 - 2n + 5 6 = 6 - 2n 2n = 0 n = 0 Check it. 6 = 1 - 0 + 5 It checks.
let the number be n. Then: 2n = 3n ⇒ 2n - 2n = 3n - 2n ⇒ 0 = n ie, the number is zero.
The value of n is 12.5
