To solve for n, you need to isolate it on one side of the equation. In this case, you can divide both sides of the equation by 2 to find the value of n. So, n = 256 / 2 = 128. Therefore, the value for n in the equation 256 = 2n is 128.

256 = 2n128 = n
2n plus 7 equals 19 2n equals 12 n equals 6
It is an equation and the value of n is 14
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
