10n+12 = 14n-12 10n-14 = -12-12 -4n = -24 n = 6
10n + 3 = 7n + 53n = 2n = 2/3
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

The n is an unknown variable.
If: 10n = 1,000,000 Then: n = 100,000
10n = 80.n = 8.
If: 10N = 25 Then: N = 2.5
10n + 3 = 93 Therefore, 10n = 90 n = 90/10 n = 9
10n = 90; divide both sides by 10 n = 9
n2 = 10n + 56 Subtract (10n + 56) from each side: n2 - 10n - 56 = 0 Now you have something on the left side that you can factor: (n - 14) (n + 4) = 0 n = +14 n = - 4
N= 2/5! :)
60/10 = 6.
n = 26
10n+12 = 14n-12 10n-14 = -12-12 -4n = -24 n = 6
10n + 3 = 7n + 53n = 2n = 2/3
10n = 7n + 4 + 2n so 10n = 9n + 4 Subtract 9n from both sides: n = 4
