2n+5's value depends on what the value of n is.When given a value for n, multiply n by 2, and add 5 to that number.
-2n +7 when n=3?
5m+n = 37 m-2n = 14 => m = 2n+14 Substitute the value of m into the top equation: 5(2n+14)+n = 37 10n+70+n = 37 10n+n = 37-70 11n = -33 Divide both sides by 11 to find the value of n: n = -3 Substitute the value of n into the original equations to find the value of m: Therefore: n = -3 and m = 8
If you mean: 2n = 5-2 then n = 1.5
2n plus 7 equals 19 2n equals 12 n equals 6
2n plus 5 n would be 7n and its impossible to solve the value of n.

If x is the smallest odd integer, then x = 2n + 1 for some integer n. Then the next two odd integers are 2n + 3 and 2n + 5 So the question then becomes: 2n+1 + (2n+3) + (2n+5) = 45 or 6n + 9 = 45 to be solved for n and thence the smallest of the three consecutive odd integers.
-2n +7 when n=3?
Let the lower value item cost $n. Then the higher value item costs $(n + 10).n + (n + 10) = 100 : 2n + 10 = 100 : 2n = 90 : n = 45 therefore n + 10 = 55.The two items cost $45 and $55.
5m+n = 37 m-2n = 14 => m = 2n+14 Substitute the value of m into the top equation: 5(2n+14)+n = 37 10n+70+n = 37 10n+n = 37-70 11n = -33 Divide both sides by 11 to find the value of n: n = -3 Substitute the value of n into the original equations to find the value of m: Therefore: n = -3 and m = 8
5-2n=3 -2n=3-5 -2n=-2 n=1
The notation 2N typically means double the amount of a variable or object N. So, 2N is twice the value of N.
If you mean: 2n = 5-2 then n = 1.5
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.
2n plus 7 equals 19 2n equals 12 n equals 6
