2n plus 7 equals 19 2n equals 12 n equals 6
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
2n + 6 = 3 + n ; this is an equation of one variable {n}. It can be solved for a value of n:subtract n fro both sides: 2n + 6 - n = 3 + n - n ---> n + 6 = 3.subtract 6 from both sides: n + 6 - 6 = 3 - 6 ---> n = -3. You should then substitute n=-3 back into the original to check your work.2(-3) + 6 = -6 + 6 = 0 | 3 + (-3) = 0, so it checks out.
N=l-m
n = 3/2, n = 2
2n plus 7 equals 19 2n equals 12 n equals 6
n = 1
-6
Solve for n. 6 = 1 - 2n + 5 6 = 6 - 2n 2n = 0 n = 0 Check it. 6 = 1 - 0 + 5 It checks.
12+4n = 2n12+4n-4n = 2n-4n12 = -2n-1/2(12 = -2n)-6 = n
n = -6
Well, if 6 equals 1 plus five, the 2n you put in the middle must be nothing. Think. n=0 Sorry If it's not right

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
n=-9.6
2n + 19 = -7 2n = -7 - 19 2n = -26 n= -13
3n + 2n = 25 5n = 25 n = 5
