n= -2
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.
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
2n/3 = 4 2n = 3*4 2n = 12 n = 6 :)
n + 2 = 5, solve for n.n = 5 - 2n = 3
2(2n + 5) = 12 2n + 5 = 6 2n = 1 n = 1/2
2n plus 7 equals 19 2n equals 12 n equals 6
n= -2
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.
N=l-m
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
2n/3 = 4 2n = 3*4 2n = 12 n = 6 :)
Solve for n. 2n+3=0 2n=-3 n=-3/2
n + 2 = 5, solve for n.n = 5 - 2n = 3
6n -3=2n+9 6n-2n=9+3 4n=12 n=12/4 n=3
Solve for n. 6 = 1 - 2n + 5 6 = 6 - 2n 2n = 0 n = 0 Check it. 6 = 1 - 0 + 5 It checks.
It can be simplified to: 9m-2n
