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 plus 7 equals 19 2n equals 12 n equals 6

3n+5=2n+7 subtract 2n on both sides. n+5=7 subtract 5 to the other side. n=2 the answer to n is 2. Hoped that helped. (:

-6

3n + 9 = 3(n + 3)

Right now, there is no solution. The sum of 2n and 12 will vary according to the value of n. If 2n + 12 = 0, then n = -6

3n + 2n = 25 5n = 25 n = 5

Solve for n. 6 = 1 - 2n + 5 6 = 6 - 2n 2n = 0 n = 0 Check it. 6 = 1 - 0 + 5 It checks.

is eassy

n + 2 = 5, solve for n.n = 5 - 2n = 3

6=(1-2n)+5 6-5=(1-2n)+5-5 1=1-2n 1-1=1-1-2n 0=-2n 0/-2=-2n/-2 0=n

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
