It is an equation and the value of n is 14
2n + 5 = 25 < ---------------- Write the Equation 2n = 20
Given that 2n = 6 + n, subtract n from each side and n = 6
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
2n+2n equals 4n
2n + 19 = -7 2n = -7 - 19 2n = -26 n= -13
-7 = 2n + 19 Subtract 19 from both side -26 = 2n Divide by 2 on both sides n = -13
-6
2(10)+1
You can't. 17 + 2n = 21 + 2n gives: 2n = 4 + 2n which gives 0=4 which is not possible so the sum is not solveable.
2n + 8 = -142n = -22n = -11
9 - 5n
10
15m + (2n-6m) + 11m = = 15m + 11m + 2n - 6m = 26m - 6m + 2n = 20m + 2n = 2(10m + n)
3 + 3n = 9 + 2n + 4n n = -2
Move the 2n over the equals sign. Become 4n (as 6n-2n= 4n) and then if 4n=16 then n=4.
2n plus 5 n would be 7n and its impossible to solve the value of n.
